Аннотация: We present an element selective resonant magnetic x-ray scattering study of NdFe3(BO3)4 as a function of temperature and applied magnetic field. Our measurements show that the magnetic order of the Nd sublattice is induced by the Fe spin order. When a magnetic field is applied parallel to the hexagonal basal plane, the helicoidal spin order is suppressed and a collinear ordering, where the moments are forced to align in a direction perpendicular to the applied magnetic field, is stabilized. This result excludes a noncollinear spin order as the origin of the magnetically induced electric polarization in this compound. Instead our data imply that magnetic frustration results in a phase competition, which is the origin of the magnetoelectric response.
Мы представляем селективное по элементам исследование резонансного магнитного рассеивания рентгеновских лучей в NdFe3(BO3)4 как функцию от температуры и приложенного магнитного поля. Наши измерения показывают, что магнитный порядок в Nd подрешетке вызван упорядочением спинов Fe. Когда магнитное поле приложено параллельно шестиугольной основной плоскости, геликоидальное упорядочение спинов подавляется, и стабилизируется коллинеарный порядок, где моменты выстроены перпендикулярно к приложенному магнитному полю. Этот результат исключает неколлинеарное упорядочение спинов как источник магнитоиндуцированной электрической поляризации в этом соединении. Вместо этого наши данные подразумевают, что магнитная фрустрация приводит к конкуренции фаз, которое является источником магнитоэлектрического отклика.

Phase transitions -- Rare-earth ferroborates RFe3(BO3) 4 -- Multiferroics
Аннотация: The magnetic properties of trigonal Nd0.9Dy0.1Fe3(BO3)4 substituted compound with the competitive Nd–Fe and Dy–Fe exchange interactions have been investigated. It has been shown that in Nd0.9Dy0.1Fe3(BO3)4 a spontaneous spin-reorientation transition from an ease-axis state to an easy-plane occurs near 8 K. Anomalies of the magnetization curves are observed in a spin-flop transition induced by the magnetic field B II c. The calculations were performed using a molecular-field approximation and a crystal-field model for the rare-earth subsystem. Extensive experimental data on the magnetic properties of Nd0.9Dy0.1Fe3(BO3)4 have been interpreted and good agreement between theory and experiment has been achieved using the obtained theoretical dependences.

Аннотация: Recently discovered magnetoelectricity in the rare-earth aluminum borates RAl3(BO3)4 has attracted attention due to the large values of magnetoinduced electric polarization. We have observed for the first time the magnetoelectric polarization in TbAl3(BO3)4 exhibiting anomalous temperature dependence: an electric polarization induced by in-plane magnetic field (P||a,H⊥c axis) which is small at low temperatures (4K), remarkably increases by almost an order of magnitude at high temperatures (150–300K). The observed nonmonotonic temperature behavior of the field-induced polarization, including a change of sign at ∼65–70K, is attributed to the competition of the ground and excited crystal-field states of Tb3+ ions. Quantum theory analysis, involving the combination of analytical and numerical methods, has enabled us to quantitatively describe the observed magnetic and magnetoelectric properties of TbAl3(BO3)4.
Недавно обнаруженное магнетоэлектричество в редкоземельных алюмоборатах RAl3 (BO3) 4 привлекло к себе внимание из-за больших значений магнитоиндуцированной электрической поляризации. Мы наблюдали в первый раз магнитоэлектрическую поляризацию в TbAl3 (BO3) 4, показывающую аномальную температурную зависимость: электрическая поляризация индуцируется в плоскости магнитного поля (Р | |, Н ⊥ оси с), и является небольшой при низких температурах (4K), Значительно увеличивается, почти на порядок величины, при высоких температурах (150-300 К). Наблюдаемая с изменением температуры немонотонность поляризации от поля, в том числе изменению знака на ~ 65-70 К, может быть отнесена к конкуренции между основном и возбужденном кристаллическим полем состояниями ионов ТЬ3 +. Теория квантового анализа, предполагающей сочетание аналитических и численных методов, позволила нам количественно описать наблюдаемые магнитные и магнитоэлектрические свойства TbAl3 (BO3) 4.

Аннотация: The conditions of the appearance of conical incommensurate structures have been studied analytically for a ferrimagnet with the geometrically frustrated exchange between spins in different magnetic positions (subsystems) and the competition between exchanges in one of the subsystems. The phase transition temperatures to the conical states have been determined. The types of phase transitions have been determined by the numerical minimization of the free energy and (temperature-exchange parameters) phase diagrams have been obtained.

Аннотация: The goal of the study is to determine the value of magnetocapacitance under the substitution of lanthanum for bismuth in thin LaxBi1-xFeO3 films and to find out the effect of an external bias electric field on the magnetocapacitance effect. To solve this task, the dielectric permittivity, the magnetic permeability, and the loss tangent are measured in LaxBi1-xFeO3 films in magnetic fields of up to 8 kOe in the range of temperatures 100 K < T < 1000 K. Maxima of the permittivity and permeability at low temperatures and the dependence of the permeability on the prehistory of a sample are found. An increase in the magnetocapacitance due to the substitution of lanthanum for bismuth is observed. A giant enhancement of magnetocapacitance in an external electric bias field is revealed. These phenomena are attributed to the rearrangement of the domain structure. © 2015, Pleiades Publishing, Inc.

Аннотация: The effect of an external magnetic field on permittivity has been studied in a Cu3B2O6 single crystal with a layered structure in the direction perpendicular to layers (bc-planes). It has been found that the appreciable magnetodielectric effect in the temperature range below the Neel temperature (?10 K) takes place only at one magnetic field orientation H and one crystallographic direction, i.e., H || b. Such “selectivity” of the magnetodielectric effect correlates with the anisotropic behavior of magnetic properties of the crystal. © 2016, Pleiades Publishing, Ltd.

Аннотация: Resonance modes that are due to magnetic excitations in the exchange-coupled subsystems of rare-earth ions (R = Nd3+, Sm3+, and Gd3+) and Fe3+ ions have been detected in submillimeter transmission spectra (0.1-0.6 THz) of RFe3(BO3)(4) iron borate-multiferroic single crystals. The strong interaction between spin oscillations of the Fe and R subsystems has been revealed, which determines the behavior of the modes depending on the anisotropy of the exchange splitting of the ground doublet of the R ion. It has been shown that the intensities of coupled modes (contributions to the magnetic permeability) depend strongly on the difference between the g factors of Fe and R ions. This dependence makes it possible to determine the sign of the latter g factor. In particular, a noticeable intensity of exchange Nd modes in NdFe3(BO3)(4) is due to an increase in their contribution at g(perpendicular to,parallel to)(Nd) 0, while in GdFe3(BO3)(4) with g(Gd) approximate to g(Fe) approximate to 2, the Fe and Gd contributions compensate each other and the exchange (Gd) mode is not observed. In spite of the weak interaction of Sm ions with the magnetic field, SmFe3(BO3)(4) exhibits resonance modes, which are attributed to the excitation of Sm ions through the Fe subsystem.

Аннотация: A giant magnetoelectric polarization is found in HoAl3(BO3)(4). The polarization in transverse field geometry at 70 kOe reaches 3600 mu C/m(2), which is significantly higher than reported values of linear magnetoelectric or even multiferroic compounds. The magnetostrictive effect is also measured and compared with the magnetoelectricity. The results show that spin-lattice coupling in HoAl3(BO3)(4) is extremely strong and that the magnetic field causes a large polar distortion of the ionic positions in the unit cell.

Аннотация: Magnetic and electron paramagnetic resonance (EPR) properties of EuFe3(BO3)(4) single crystals have been studied over the temperature range of 300-4.2 K and in a magnetic field up to 5 T. The temperature, field and orientation dependences of susceptibility, magnetization and EPR spectra are presented. An antiferromagnetic ordering of the Fe subsystem occurs at about 37 K. The easy direction of magnetization perpendicular to the c axis is determined by magnetic measurements. Below 10 K, we observe an increase of susceptibility connected with the polarization of the Eu sublattice by an effective exchange field of the ordered Fe magnetic subsystem. In a magnetic field perpendicular to the c axis, we have observed an increase of magnetization at T < 10 K in the applied magnetic field, which can be attributed to the appearance of the magnetic moment induced by the magnetic field applied in the basal plane. According to EPR measurements, the distance between the maximum and minimum of derivative of absorption line of the Lorentz type is equal to 319 Gs. The anisotropy of g-factor and linewidth is due to the influence of crystalline field of trigonal symmetry. The peculiarities of temperature dependence of both intensity and linewidth are caused by the influence of excited states of europium ion (Eu3+). It is supposed that the difference between the g-factors from EPR and the magnetic measurements is caused by exchange interaction between rare earth and Fe subsystems via anomalous Zeeman effect.

Аннотация: We have studied the magnetodielectric and magnetoelastic coupling in TbFe3(BO3)(4) single crystals by means of capacitance, magnetostriction, and Raman spectroscopy measurements. The data reveal strong magnetic field effects on the dielectric constant and on the macroscopic sample length which are associated to long-range magnetic ordering and a field-driven metamagnetic transition. We discuss the coupling of the dielectric, structural, and magnetic order parameters and attribute the origin of the magnetodielectric coupling to phonon mode shifts according to the Lyddane-Sachs-Teller relation.

Аннотация: The magnetic properties, the magnetostriction, and the magnetoelectric effect in the d-electron free rare-earth aluminum borate TmAl3(BO3)(4) are investigated between room temperature and 2 K. The magnetic susceptibility reveals a strong anisotropy with the hexagonal c axis as the hard magnetic axis. Magnetostriction measurements show a large effect of an in-plane field reducing both the a-axis and c-axis lattice parameters. The magnetoelectric polarization change in a and c directions reaches up to 300 mu C/ m(2) at 70 kOe with the field applied along the a axis. The magnetoelectric polarization is proportional to the lattice contraction in magnetic field. The results of this investigation prove the existence of a significant coupling between the rare-earth magnetic moment and the lattice in RAl3(BO3)(4) compounds (R=rare earth). They further show that the rare-earth moment itself will generate a large magnetoelectric effect which makes it easier to study and to understand the origin of the magnetoelectric interaction in this class of materials.

Аннотация: The magnetic and magnetoelectric properties of a single crystal of Ho0.25Nd0.75Fe3(BO3)(4) have been investigated along the main crystallographic directions. The spontaneous polarization starts increasing below the Neel temperature T-N similar to 32 K and it displays a sudden drop at 4.8 K. This sharp decrease suggests the existence of a spin reorientation phase transition. In this compound, both spontaneous polarization and the polarization due to the magnetoelectric effect exist. Detailed study of the effect of magnetic field on the polarization and the spin rotation transition has been performed. Specific heat and magnetization measurements show characteristic anomalies at both magnetic transitions. The magnetic field (H)-temperature phase diagram has completely been resolved for H parallel to c and H parallel to a axes. (C) 2010 American Institute of Physics. [doi:10.1063/1.3362915]

Аннотация: The present paper reports on the specific heat and magnetization of the YFe3(BO3)(4) and ErFe3(BO3)(4) single crystals. In both compounds, antiferromagnetic order of the iron spins evolves at T-N = 38 K. The experimental data suggest that the magnetic moments are in the basal plane of the trigonal crystal for both compounds. In the magnetically ordered state the crystal is subdivided into three types of domains, the magnetic moments of the Fe3+ ions being aligned along the a axis within each domain. For ErFe3(BO3)(4), two non-equivalent magnetic positions of the Er3+ ions in each domain are observed.

Аннотация: The thermodynamic, magnetic, dielectric, and magnetoelectric properties of HoFe3(BO3)(4) and Ho0.5Nd0.5Fe3(BO3)(4) are investigated. Both compounds show a second order Neel transition above 30 K and a first-order spin reorientation transition below 10 K. HoFe3(BO3)(4) develops a spontaneous electrical polarization below the Neel temperature (T-N) which is diminished in external magnetic fields. No magnetic-field induced increase of the polarization could be observed in HoFe3(BO3)(4). In contrast, the solid solution Ho0.5Nd0.5Fe3(BO3)(4) exhibits both, a spontaneous polarization below T-N and a positive magnetoelectric effect at higher fields that extends to high temperatures. The superposition of spontaneous polarization, induced by the internal magnetic field in the ordered state, and the magnetoelectric polarizations due to the external field results in a complex behavior of the total polarization measured as a function of temperature and field.

Аннотация: Single crystals of Pb2Fe2Ge2O9 have been grown. They were subjected to X-ray diffraction, magnetic, neutron diffraction, Mossbauer and spin resonance studies. It has been established that Pb2Fe2Ge2O9 is a weak ferromagnet with a N,el temperature T (N) = 46 K, and the exchange and spin-flop transition fields have been estimated. It has been demonstrated that the weak ferromagnetic moment is actually the result of the single-ion anisotropy axes for the magnetic moments of different magnetic sublattices being not collinear.

Аннотация: We present a resonant x-ray diffraction study of the magnetic order in NdFe3(BO3)4 and its coupling to applied electric fields. Our high-resolution measurements reveal two different coexisting magnetic phases, which can directly be controlled and manipulated by external electric fields. More specifically, the volume fraction of the collinear magnetic phase is found to strongly increase at the expense of helically ordered regions when an electric field is applied. These results confirm that the collinear magnetic phase is responsible for the ferroelectric polarization of NdFe3(BO3)4 and, more importantly, demonstrate that coexisting magnetic phases provide a route towards materials with a strong but yet hysteresis-free magnetoelectric response.

Аннотация: We report on the magnetostriction of hexagonal HoMnO3 and YMnO3 single crystals in a wide range of applied magnetic fields (up to H = 14 T) at all possible combinations of the mutual orientations of magnetic field H and magnetostriction ΔL/L. The measured ΔL/L(H, T) data agree well with the magnetic phase diagram of the HoMnO3 single crystal reported previously by other authors. It is shown that the nonmonotonic behavior of magnetostriction of the HoMnO3 crystal is caused by the Ho3+ ion; the magnetic moment of the Mn3+ ion parallel to the hexagonal crystal axis. The anomalies established from the magnetostriction measurements of HoMnO3 are consistent with the phase diagram of these compounds. For the isostructural YMnO3 single crystal with a nonmagnetic rare-earth ion, the ΔL/L(H, T) dependences are described well by a conventional quadratic law in a wide temperature range (4–100 K). In addition, the magnetostriction effect is qualitatively estimated with regard to the effect of the crystal electric field on the holmium ion.

Аннотация: The capacity and the dielectric loss tangent of a Gd x Mn1–xSe (x ≤ 0.2) solid solution have been measured in the frequency range 1–300 kHz without a magnetic field and in a magnetic field of 8 kOe in the temperature range 100–450 K, and the magnetic moment of the solid solution has been measured in a field of 8.6 kOe. The magnetocapacity effect and the change in the magnetocapacity sign have been observed in room temperature in the paramagnetic region. A correlation of the changes in the dielectric permittivity and the magnetic susceptibility with temperature has been revealed. The magnetocapacity is described using the model with orbital electron ordering and the Maxwell–Wagner model.
