Аннотация: The anisotropy of the electromechanical properties of SH-waves and Lamb waves in yttrium aluminum borates, which are nonmagnetic representatives of the RMe3(BO3)4 single crystals family (where R=Y, La-Lu; M=Fe, Al, Cr, Ga, Sc) with unique properties of magnetoelectrics and multiferroics, has been studied. In the process of the numerical simulation of the acoustic waves characteristics, the values of linear electromechanical constants of YAl3(BO3)4 single crystals, previously measured by ultrasonic pulse echo and quasi-static methods, have been used.Исследована анизотропия электромеханичеких характеристик SH-волн и волн Лэмба в иттриевых алюмоборатах, которые являются немагнитным представителем семейства монокри- сталлов RMe3(BO3)4 (где R=Y, La-Lu; M=Fe, Al, Cr, Ga, Sc) с уникальными свойствами магнитоэлектриков и мультиферроиков.

Аннотация: SmFe3(BO3)4 single crystals have been grown from the bismuth trimolybdate and lithium tungstate-based melt–solutions. Samarium ferroborate single crystals were grown first from the lithium–tungstate flux. The magnetic and magnetoelectric properties of the synthesized crystals have been compared. It is shown that the SmFe3(BO3)4 ferroborate grown from the bismuth trimolybdate-based melt–solution contains impurities of Bi3+ ions (∼5% at.), which replace Sm3+ ions, while the SmFe3(BO3)4, ferroborate grown from the lithium tungstate-based melt–solution contains minor or zero amounts of such impurities. The magnetoelectric and magnetodielectric effects with the Bi3+ admixture appeared 1.5× stronger than in SmFe3(BO3)4; this is probably due to twinning.

Аннотация: Various resonance modes were observed in the transmission spectra of rare-earth iron borates RFe 3(BO 3) 4 (R = Nd 3+, Sm 3+, Gd 3+) at the frequency range 100-600 GHz, which were attributed to collective magnetic excitations in the exchange coupled Fe- and R-subsystems, i.e. antiferromagnetic (Fe) resonance and electron transitions in the R-ions. Strong interaction of the Fe and R oscillations was revealed and theoretically analyzed taking into account feature of the R-ion ground state. Intensities of the coupled modes (contributions to magnetic permeability) strongly depend on a difference of Fe and R ions g-factors that allows defining the sign of the latter. In particular, an appreciable intensity of exchange (Nd) modes in NdFe 3(BO 3) 4 is caused by g Nd?,|| < 0 whereas in GdFe 3(BO 3) 4 with gGd ? gFe ? 2 the exchange (Gd) modes were hided due to compensation of Fe and Gd contributions. In SmFe 3(BO 3) 4, despite a negligible Sm g-factor, the Sm modes were clear observed due to their excitation via coupling with the Fe-subsystem. В© (2012) Trans Tech Publications.

Заглавие : Crystal growth of ReCa3Mn3O3(BO3)4 (Re = Gd, Y) gaudefroyite: Phase sequence and equilibrium study in multi-component fluxes
Место публикации : J. Cryst. Growth. - 2022. - Vol. 600. - Ст.126917. - ISSN 00220248 (ISSN), DOI 10.1016/j.jcrysgro.2022.126917
Примечания : Cited References: 32. - The study was supported by the Russian Science Foundation (grant No. 21-72-00130).

Аннотация: The work is aimed at studying the crystallization of ReCa3Mn3O3(BO3)4 (Re = Gd, Y) borates with the gaudefroyite structure in different flux systems. Gaudefroyites are promising materials in the field of spin ice and magnetocaloric effect. The study has been performed on systems based on the following solvents: Bi2Mo3O12-Na2B4O7-B2O3, Bi2O3-Na2B4O7-B2O3, Bi2O3-BaO-Na2B4O7-B2O3, Li2WO4-Li2O-B2O3. The influence of the solvent components on the sequence of high-temperature crystallizing phases has been studied. The feature of Mo- and W-containing fluxes consisting in the formation of stable chemical bonds of the M2+Mo(W)O4 (M = Ca, Mn) molybdate or tungstate types has been revealed which prevents the formation of gaudefroyite type bonds. An approach has been suggested for changing the sequence of the crystallizing phases which consists in the super saturation of molybdate (tungstate) bonds by Na+ or Li+ cations up to the formation of delafossite-type bonds (Li(Na)-Mn-O phase) with higher manganese valence states Mn3+ and Mn4+. The optimization of the growth conditions of ReCa3(MnO)3(BO3)4 (Re = Gd, Y) gaudefroyite crystals has allowed one to obtain single crystal samples with the size up to 0.8 × 0.8 × 5 mm3. The structural characterization and chemical composition of all the obtained phases are also presented.

Заглавие : Crystal structure dynamics of RFe3(BO3)4 single crystals in the temperature range 25–500 K
Место публикации : Crystals. - 2022. - Vol. 12, Is. 9. - Ст.1203. - ISSN 20734352 (ISSN), DOI 10.3390/cryst12091203

Аннотация: The multiferroic RFe3(BO3)4 family is characterized by diverse magnetic, magnetoelectric, and magnetoelastic properties, the fundamental aspects of which are essential for modern electronics. The present research, using single-crystal X-ray diffraction (XRD) and Mossbauer spectroscopy (MS) in the temperature range of 25–500 K, aimed to analyze the influence of local atomic coordination on magnetoelectric properties and exchange and super-exchange interactions in RFe3(BO3)4. Low-temperature, single-crystal XRD data of the magnetically ordered phase of RFe3(BO3)4 at 25 K, which were obtained for the first time, were supplemented with data obtained at higher temperatures, making it possible to draw conclusions about the mechanism of the structural dynamics. It was shown that, in structures with R = Gd, Ho, and Y (low-temperature space group P3121), a shift in oxygen atoms (O2, second coordination sphere of R atoms) was accompanied by rotation of the B2O3 triangle toward R atoms at low temperatures, and by different rearrangements in iron chains of two types, in contrast to Nd and Sm iron borates (space group R32). These rearrangements in the structures of space group P3121 affected the exchange and super-exchange paths at low temperatures. The MS results confirm the influence of the distant environment of atoms on the magnetoelectric properties of rare-earth iron borates at low temperatures.

Аннотация: Structural features of new mixed bismuth-containing samarium iron–aluminium borate single crystals Sm1−xBixFe3−yAly(BO3)4 (x = 0.05–0.07, y = 0–0.28) were studied using X-ray diffraction analysis based on aluminium content and temperature in the range 25–500 K. The crystals were grown using the solution-in-melt technique with Bi2Mo3O12 in a flux. The composition of the single crystals was analyzed using energy-dispersive X-ray fluorescence and energy-dispersive X-ray elemental analysis. Temperature dependencies of Sm1−xBixFe3−yAly(BO3)4 unit-cell parameters were studied. Negative thermal expansion was identified below 100 K and represented by characteristic surfaces of the thermal expansion tensor. (Sm,Bi)–O, (Sm,Bi)–(Fe,Al), (Fe,Al)–(Fe,Al), and (Fe,Al)–O interatomic distances decreased with the addition of aluminium atoms. An increase in the (Fe,Al)–(Fe,Al) intrachain bond length at low temperatures in the magnetically ordered state weakened this bond, whereas a decrease in the (Fe,Al)–(Fe,Al) interchain distance strengthened super-exchange paths between different chains. It was found that the addition of aluminium atoms influenced interatomic distances in Sm1−xBixFe3−yAly(BO3)4 much more than lowering the temperature from 293 K to 25 K. The effect of aluminium doping on magnetoelectric properties and structural symmetry of rare-earth iron borates is also discussed.

Аннотация: An accurate X-ray diffraction study of (Y0.95Bi0.05)Fe3(BO3)4 single crystals in the temperature range 90–500 K was performed on a laboratory diffractometer and used synchrotron radiation. It was established that the crystal undergoes a diffuse structural phase transition in the temperature range 350–380 K. The complexity of localization of such a transition over temperature was overcome by means of special analysis of systematic extinction reflections by symmetry. The transition temperature can be considered to be Tstr ≃ 370 K. The crystal has a trigonal structure in the space group P3121 at temperatures of 90–370 K, and it has a trigonal structure in the space group R32 at 375–500 K. There is one type of chain formed by the FeO6 octahedra along the c axis in the R32 phase. When going into the P3121 phase, two types of nonequivalent chains arise, in which Fe atoms are separated from the Y atoms by a different distance. Upon lowering the temperature from 500 to 90 K, a distortion of the Y(Bi)O6, FeO6, B(2,3)O3 coordination polyhedra is observed. The distances between atoms in helical Fe chains and Fe—O—Fe angles change non-uniformly. A sharp jump in the equivalent isotropic displacement parameters of O1 and O2 atoms within the Fe—Fe chains and fluctuations of the equivalent isotropic displacement parameters of B2 and B3 atoms were observed in the region of structural transition as well as noticeable elongation of O1, O2, B2, B3, Fe1, Fe2 atomic displacement ellipsoids. It was established that the helices of electron density formed by Fe, O1 and O2 atoms may be structural elements determining chirality, optical activity and multiferroicity of rare-earth iron borates. Compression and stretching of these helices account for the symmetry change and for the manifestation of a number of properties, whose geometry is controlled by an indirect exchange interaction between iron cations that compete with the thermal motion of atoms in the structure. Structural analysis detected these changes as variations of a number of structural characteristics in the c unit-cell direction, that is, the direction of the helices. Structural results for the local surrounding of the atoms in (Y0.95Bi0.05)Fe3(BO3)4 were confirmed by EXAFS and Mössbauer spectroscopies.

Аннотация: Temperature dependent neutron diffraction studies were performed on SmFe3(BO3)4. The crystallographic structure was determined to stay as R32 over the whole studied temperature range of 2 K ‹ T ‹ 300 K. A magnetic phase transition characterized by the magnetic propagation vector κ = [0 0 3/2] takes place at TN = 34 K. The magnetic structure sees an easy-plane arrangement within the trigonal basal a–b-plane of ferromagnetic layers of iron and samarium having a canting angle of about 70° relative to each other. Neighbouring layers in the c-direction are antiferromagnetically coupled; at 2 K the magnetic moment values amount to μFe = 4.2(1) μB and μSm = 0.8(2) μB. The non-Brillouin type increase of the iron magnetic moment below TN points to a strong Fe–Sm exchange and to the simultaneous appearance of long range magnetic order on both sublattices.

Аннотация: Single crystalline Mn2-xFexBO4 with x = 0.3, 0.5, 0.7 grown by the flux method have been studied by means of X-ray diffraction and X-ray absorption spectroscopy at both Mn and Fe K edges. The compounds were found to crystallize in an orthorhombic warwickite structure (sp. gr. Pnam). The lattice parameters change linearly with x thus obeying the Vegard's law. The Fe3+ substitution for Mn3+ has been deduced from the X-ray absorption near-edge structure (XANES) spectra. Two energy positions of the absorption edges have been observed in Mn K-edge XANES spectra indicating the presence of manganese in two different oxidation states. Extended X-ray absorption fine structure (EXAFS) analysis has shown the reduction of local structural distortions upon Fe substitution. The magnetization data have revealed a spin-glass transition at TSG = 11, 14 and 18 K for x = 0.3, 0.5 and 0.7, respectively.

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 phase formation of terbium chromoborate TbCr3(BO3)4 in the bismuth trimolybdate and lithium tungstate melt–solutions has been studied. The absence of the terbium chromoborate trigonal phase in the bismuth trimolybdate-based system at all component ratios has been shown. The component ratio in the lithium tungstate-based system has been found at which the TbCr3(BO3)4 trigonal crystals are formed at temperatures above 1100 °C; below this temperature, the monoclinic phase dominates. The structural and magnetic properties of the grown crystals have been studied. It has been established that the trigonal and monoclinic TbCr3(BO3)4 crystals synthesized from the lithium tungstate-based solvent exhibit identical magnetic properties. At the same time, a significant difference of the magnetic properties of the single crystals synthesized from the bismuth molybdate melt–solution has been observed. This difference has been attributed to the effect of Bi3+ ions that partially replace Tb3+ ions.

Аннотация: Orthorhombic bismuth triborate (delta-BiB3O6) Single crystals were grown via the top-seeded method at atmospheric pressure. delta-BiB3O6 is shown to be a stable polymorph at temperatures close to the melting point while alpha-BiB3O6 is a metastable one. Optical, acoustic and electromechanical properties of delta-BiB3O6 are measured. Possibility of doping delta-BiB3O6 with large amounts of rare earths is demonstrated.

Аннотация: Temperature-dependent high-resolution optical spectra of the Er3+ probe ion in DyFe3(BO3)(4) and HoFe3(BO3)(4) are reported. The data provide the temperature of magnetic ordering and direction of the Fe3+ magnetic moments. Both compounds order magnetically at T-N = 39 +/- 1K. The magnetic structure of DyFe3(BO3)(4) is of the easy-axis type, while that of HoFe3(BO3)(4) is of the easy-plane type. The role of anisotropic interactions between the iron and the rare-earth subsystems is discussed. (c) 2007 Elsevier B.V. All rights reserved.

Заглавие : Magnetic anisotropy of the VBO3 and CrBO3 transition-metal borates
Место публикации : Phys. Solid State: AMER INST PHYSICS, 2003. - Vol. 45, Is. 2. - P287-291. - ISSN 1063-7834, DOI 10.1134/1.1553533

Аннотация: Temperature and field dependences of the magnetization of VBO3 and CrBO3 single crystals with the magnetic field applied parallel and perpendicular to the (111) basal plane were measured. VBO3 was found to have a considerable uniaxial anisotropy with a field H-a approximate to 6.25 T. CrBO3 was shown to exhibit not only uniaxial but also hexagonal anisotropy. The experimental anisotropy constants were estimated, and their temperature dependences are presented. (C) 2003 MAIK "Nauka / Interperiodica".
