Аннотация: The crystal structure and magnetic properties of Co3B2O6 single crystals are studied. Orthorhombic symmetry with space group Pnnm is detected at room temperature. The measurements of static magnetization and dynamic magnetic susceptibility reveal two magnetic anomalies at T (1) = 33 K and T (2) = 10 K and an easy-axis magnetic anisotropy. The effective magnetic moment indicates a high-spin state of the Co2+ ion. A spin-flop transition is found at low temperatures and H (sf) = 23 kOe. EXAFS spectra of the K-edge absorption of Co are recorded at various temperatures, the temperature-induced changes in the parameters of the local environment of cobalt are analyzed, and the effective Co-Co and Co-O distances are determined. The magnetic interactions in the crystal are analyzed in terms of an indirect coupling model.

Аннотация: Polarized optical absorption and magnetic circular dichroism (MCD) spectra of the trigonal multiferroic Nd0.5Gd0.5Fe3(BO3)4 were studied in the region of transitions 4I9/2 → 4F3/2 and 4I9/2 → (4F5/2 + 2H9/2) in Nd3+ ion. Components of the crystal field splitting of the states were identified with the help of MCD and polarized absorption spectra. Splitting of the Nd3+ absorption lines caused by the magnetic ordering were observed. Splitting of Nd3+ ground state in Fe-sublattice exchange field was found to be ∼9 cm−1 at 5.7 K. The Zeeman splitting of some absorption lines in the external magnetic field and changes of the effective Landé factors in the C3-direction as a result of the corresponding optical transitions were found. Peculiarities in the temperature behavior of the absorption lines connected both with the ground and excited states were revealed. Peculiarities connected with the excited states testify to the local crystal distortions in the excited states.

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: Neutron diffraction and Mossbauer spectroscopy have been used to examine the connections between long-and short-range magnetic order in the rare-earth iron ferroborate YFe3(BO3)(4). We establish the presence of short-range magnetic order in the pseudo-one-dimensional Fe-spin chains of the FeO6 octahedra while the ferroborates are in their (long-range) paramagnetic phase. The short-range order exists at temperatures several times the Neel temperature. In addition, we observe thermal hysteresis of the short-range ordered Fe spins. The observed Fe-spin dynamics are suggestive of the presence of solitons within the domains that form in the Fe-spin chains.

Аннотация: The magnetoresonance and dielectric properties of a number of crystals of a new family of multiferroics, namely, rare-earth ferroborates RFe(3)(BO(3))(4) (R = Y, Eu, Pr, Tb, Tb(0.25)Er(0.75)), are studied in the submillimeter frequency range (nu = 3-20 cm(-1)). Ferroborates with R = Y, Tb, and Eu exhibit permittivity jumps at temperatures of 375, 198, and 58 K, respectively, which are caused by the R32 -> P3(1)2(1) phase transition. Antiferromagnetic resonance (AFMR) modes in the subsystem of Fe(3+) ions are detected in the range of antiferromagnetic ordering (T < T(N) = 30-40 K) in all ferroborates that have either an easy-plane (Y, Eu) or easy-axis (Pr, Tb, Tb(0.25)Er(0.75)) magnetic structure. The AFMR frequencies are found to depend strongly on the magnetic anisotropy of a rare-earth ion and its exchange interaction with the Fe subsystem, which determine the type of magnetic structure and the sign and magnitude of an effective anisotropy constant. The basic parameters of the magnetic interactions in these ferroborates are found, and the magnetoelectric contribution to AFMR is analyzed.

Аннотация: The magnetic properties of the Nd0.5Gd0.5Fe3(BO3)(4) single crystal have been studied in principal crystallographic directions in magnetic fields to 90 kG in the temperature range 2-300 K; in addition, the heat capacity has been measured in the range 2-300 K. It has been found that, below the N,el temperature T (N) = 32 K down to 2 K, the single crystal exhibits an easy-plane antiferromagnetic structure. A hysteresis has been detected during magnetization of the crystal in the easy plane in fields of 1.0-3.5 kG, and a singularity has been found in the temperature dependence of the magnetic susceptibility in the easy plane at a temperature of 11 K in fields B 1 kG. It has been shown that the singularity is due to appearance of the hysteresis. The origin of the magnetic properties of the crystal near the hysteresis has been discussed.

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: The IR reflection spectra of a TbFe3(BO3)(4) crystal are measured in the spectral range 200-2000 cm(-1) in E perpendicular to c polarization at temperatures 10 and 300 K. The reflection spectrum so obtained is analyzed and its interpretation is given on the basis of the internal vibrations of the ionic complexes BO33-, FeO69-, and TbO69- of the TbFe3(BO3)(4) crystal. Davydov splitting on the internal vibrational modes at a structural phase transition, which is accompanied by multiplication of the unit cell, was not observed in the experimental spectral range. This is due to the localization of the vibrations of the ionic complexes BO33-, FeO69-, and TbO69- of the TbFe3(BO3)(4) crystal. (c) 2010 American Institute of Physics. [doi:10.1063/1.3479413]

Аннотация: Neutron diffraction, susceptibility and magnetization measurements (for R = Er only) were performed on iron borates RFe3(BO3)(4) (R = Pr, Er) to investigate details of the crystallographic structure, the low temperature magnetic structures and transitions and to study the role of the rare earth anisotropy. PrFe3(BO3)(4), which crystallizes in the spacegroup R32, becomes antiferromagnetic at T-N = 32 K, with t = [0 0 3/2], while ErFe3(BO3)(4), which keeps the P3(1)21 symmetry over the whole studied temperature range 1.5 K < T < 520 K, becomes antiferromagnetic below T-N = 40 K, with tau = [0 0 1/2]. Both magnetic propagation vectors lead to a doubling of the crystallographic unit cell in the c-direction. Due to the strong polarization of the Fe-sublattice, the magnetic ordering of the rare earth sublattices appears simultaneously at T-N. The moment directions are determined by the rare earth anisotropy: easy-axis along c for PrFe3(BO3)(4) and easy-plane a-b for ErFe3(BO3)(4). There are no spin reorientations present in either of the two compounds but there is the appearance below 10 K of a minority phase in the Er-compound adopting a 120 degrees arrangement of the Er-moments.

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.
