Аннотация: The results are given of experimental and theoretical study for the photoinduced variation of the magnetic moment in FeBO3. In the experiment a SQUID-magnetometer provided with the optical pump system is used. The study of field, temperature and time dependences of the photoinduced magnetic moment variation for various levels of the optical emission power allows to find the mechanism responsible for changing magnetic state under irradiation. All the experimental results are explained within the model in which the crystal-matrix is described in the continual approximation and a photocenter, probably, Fe2+ ion is done as a quasi Ising S=1 ion coupled by exchange with one of the crystal magnetic sublattice. Under illuminating the redistribution of the principal multiplet level populations occurs so that the level of the stronger anisotropic character is populated predominantly due to the selection rules. The model used allows to calculate and explain the anisotropic properties of FeBO3 crystals and spin-flip transition in the basal plane at low temperature.

Structural and electronic transitions in gadolinium iron borate GdFe3(BO3)(4) at high pressures / A. G. Gavriliuk [et al.] // JETP Letters. - 2004. - Vol. 80, Is. 6. - P. 426-432, DOI 10.1134/1.1830662. - Cited References: 20 . - ISSN 0021-3640

Аннотация: The optical properties and structure of gadolinium iron borate GdFe3(BO3)(4) crystals are studied at high pressures produced in diamond-anvil cells. X-ray diffraction data obtained at a pressure of 25.6 GPa reveal a first-order phase transition retaining the trigonal symmetry and increasing the unit cell volume by 8%. The equation of state is obtained and the compressibility of the crystal is estimated before and after the phase transition. The optical spectra reveal two electronic transitions at pressures similar to26 GPa and similar to43 GPa. Upon the first transition, the optical gap decreases jumpwise from 3.1 to similar to2.25 eV. Upon the second transition at P = 43 GPa, the optical gap deceases down to similar to0.7 eV, demonstrating a dielectric-semiconductor transition. By using the theoretical model developed for a FeBO3 crystal and taking into account some structural analogs of these materials, the anomalies of the high-pressure optical spectra are explained.

Аннотация: The optical spectra and the second-harmonic generation (SHG) are studied in a noncentrosymmetric GdFe3(BO3)(4) magnet. In the region of weak absorption (alpha similar to 20-400 cm(-1)) below similar to3 eV, three absorption bands are distinguished, which can be unambiguously assigned to forbidden electronic transitions from the ground (6)A(1) state of the Fe3+ ion to its excited states T-4(1) (similar to1.4 eV), T-4(2) (similar to2 eV), and (4)A(1), E-4 (similar to2.8 eV). Intense absorption begins in the region above 3 eV (alpha similar to 2-4 x 10(5) cm(-1)), where two bands at similar to4.0 and 4.8 eV are observed, which are caused by allowed electric dipole charge-transfer transitions. The spectral features of SHG in the 1.2-3.0-eV region are explained by a change in the SHG efficiency caused by a change in the phase mismatch. It is shown that in the weak absorption region, phase matching can be achieved for SHG. (C) 2004 MAIK "Nauka / Interperiodica".

Аннотация: A many-electron model of the energy band structure of VBO3 and of Fe1 - xVxBO3 solid solutions is proposed with strong electron correlations taken into account. Experimental optical absorption spectra and data on the resistivity are discussed in the framework of the suggested model. Variation in the magnetic and electronic properties of VBO3 and Fe1 - xVxBO3 under high pressure is predicted. For VBO3, a Mott-Hubbard (insulator-metal) transition is expected in the high-pressure phase. In Fe1 - xVxBO3 solid solutions, a nontrivial variation in the properties is predicted, leading to the appearance of a different magnetic state. (C) 2004 MAIK "Nauka / Interperiodica".

Аннотация: The Mossbauer effect in the Fe1 - xVxBO3 solid solutions has been measured at 130 and 300 K. The Fe0.05V0.95BO3 composition was studied in the interval 4.2-300 K. The experimental data obtained are described in terms of the model of a dilute magnetic insulator in which atoms of the first coordination sphere provide a major contribution to the hyperfine field at iron nucleus sites. It was found that, at low temperatures, the field H-hf is generated primarily by the iron ion itself and depends only weakly on substitution. The hyperfine interaction parameters in the discrete configuration series 6Fe, 5Fe1V, 4Fe2V, 3Fe3V, and 2Fe4V were determined. The magnitude of the isomer shift suggests that iron in the crystal resides in the trivalent state. (C) 2004 MAIK "Nauka/Interperiodica".

Аннотация: The transformation of various properties of gadolinium ferroborate single crystals at phase transitions, both spontaneous and induced by magnetic fields up to 200 kOe, is investigated theoretically and experimentally. Particular attention is paid to elucidating the role of magnetoelectric interactions and the change in them at spin-reorientation transitions accompanied by a change of magnetic symmetry. With that goal the magnetoelastic and magnetoelectric properties of the system are investigated over a wide range of temperatures for two orientations of the magnetic field, H parallel to c and H perpendicular to c, and a fundamental difference of the character of the field dependences of the magnetostriction and electric polarization is found. In the framework of a symmetry approach a description of the magnetic structures and their transformations in the system GdFe3(BO3)(4) is proposed, and an interpretation of the experimentally observed properties is given.

Аннотация: For the first time the problem of determining real composition and structure of manganese ferrite nanoparticles dispersed borate glasses is solved using differentiating dissolution and high-resolution X-ray electron microscopy techniques. For the first time the nanosize effect of aluminum incorporation in manganese ferrite composition is experimentally shown, thus directly confirming the hypothesis of Al participation in exchange interaction between paramagnetic Fe and Mn ions as diamagnetic diluter.

Аннотация: The high-pressure magnetic states of iron borate (FeBO3)-Fe-57 single-crystal and powder samples have been investigated in diamond anvil cells by nuclear forward scattering (NFS) of synchrotron radiation at different temperatures. In the low-pressure (0 < P < 46 GPa) antiferromagnetic phase, an increase of the Neel temperature from 350 to 595 K induced by pressure was found. At pressures 46-49 GPa, a transition from the antiferromagnetic to a new magnetic state with a weak magnetic moment (magnetic collapse) was discovered. It is attributed to the electronic transition in Fe3+ ions from the high-spin 3d(5) (S = 5/2, (6)A(1g)) to the low-spin (S = 1/2, T-2(2g)) state (spin crossover) due to the insulator-semiconductor-type transition with extensive suppression of strong d-d electron correlations. At low temperatures, NFS spectra of the high-pressure phase indicate magnetic correlations in the low-spin system with a magnetic ordering temperature of about 50 K. A tentative magnetic P-T phase diagram of FeBO3 is proposed. An important feature of this diagram is the presence of two triple points where magnetic and paramagnetic phases of the high-spin and low-spin states coexist. © 2005 Pleiades Publishing, Inc.

Аннотация: Magnetoelectric interactions have been investigated in a single crystal of gadolinium iron borate GdFe3(BO3)(4), whose macroscopic symmetry is characterized by the crystal class 32. Using the results of this study, the interplay of magnetic and electric orderings occurring in the system has been experimentally revealed and theoretically substantiated. The electric polarization and magnetostriction of this material that arise in spin-reorientation transitions induced by a magnetic field have been investigated experimentally. For H parallel to c and H perpendicular to c, H-T phase diagrams have been constructed, and a strict correlation between the changes in the magnetoelectric and magnetoelastic properties in the observed phase transitions has been ascertained. A mechanism of specific noncollinear antiferroelectric ordering at the structural phase transition point was proposed to interpret the magnetoelectric behavior of the system within the framework of the symmetry approach in the entire temperature range. This ordering provides the conservation of the crystal class of the system when the temperature decreases to the antiferroelectric ordering point. The expressions that have been obtained for the magnetoelectric and magnetoelastic energy describe reasonably well the behavior of gadolinium iron borate observed experimentally.

Аннотация: Magnetic susceptibility, electron paramagnetic resonance (EPR), and optical properties have been studied in a glass system {20La(2)O(3)-22Al(2)O(3)-23B(2)O(3)-35(SiO2+GeO2)} with a part of La2O3 substituted by Gd2O3 in different concentrations. Positive Weiss constants have been found in the more heavily doped glasses and ascribed to clustering of Gd3+ ions. Two magnetic phase transitions at 55 and 12 K were detected and ascribed, respectively, to ferromagnetic and antiferromagnetic clusters containing Gd ions. The overall shape of the EPR spectra shows the presence of clustering at the higher Gd contents. At low temperatures the cluster-related resonance signal is altered in shape, indicating an onset of magnetic anisotropy field. This signal is convincingly fitted to superparamagnetic resonance arising from ferromagnetic nanoparticles. The clustering, depending on the Gd concentration, correlates with a significant shift to lower energies of the strong optical absorption band edge, ascribed to a charge transfer transition between Gd ions. A nonmonotonous change of refractive index with the increase of the Gd content indicates changes in the glass matrix and in Gd cluster structure.

Аннотация: GdFe3(BO3)(4) exhibits a structural phase transition at 156 K, antiferromagnetic order of the Fe3+ moments at 36 K, followed by a spin reorientation phase transition at 9 K. The reorientation phase transition is studied through dielectric, magnetic, and heat capacity measurements under the application of external magnetic fields of up to 7 kOe. The dielectric constant indicates the existence of two distinct anomalies at T-SR=9 K that separate in temperature under external magnetic fields. The spin rotation phase transition is proven to be of the first-order nature through the magnetic analog of the Clausius-Clapeyron equation. Magnetodielectric effect of up to 1% is observed at 8 K and 7 kOe. The uniaxial magnetocaloric effect along the c axis is observed below the spin reorientation phase transition of 9 K.

Аннотация: Inelastic light scattering spectra of several members of the RFe3(BO3)(4) family reveal a cascade of phase transitions as a function of temperature, starting with a structural, weakly first-order, phase transition followed by two magnetic phase transitions. Those consist of the ordering of the Fe-spin sublattice, revealed by all the compounds, and a subsequent spin-reorientational transition for GdFe3(BO3)(4). The Raman data evidence a strong coupling between the lattice and magnetic degrees of freedom in these borates. The Fe-sublattice ordering leads to a strong suppression of the low-energy magnetic scattering, and a multiple peaked two-magnon scattering continuum is observed. Evidence for short-range correlations is found in the "paramagnetic" phase by the observation of a broad magnetic continuum in the Raman data, which persists up to surprisingly high temperatures.

Аннотация: B-11 nuclear magnetic resonance (NMR) spectroscopy was applied to study the crystalline, amorphous and crystallizing from an amorphous states of copper metaborate. The occurrence of trigonal BO3 units at the expense of converting tetragonal BO4 units was observed in amorphous CuB2O4. This fact explains the essential change of CuB2O4 magnetic properties under amorphization.

Аннотация: The optical absorption and luminescence spectra of single crystals of yttrium aluminum borate YAl3(BO3)(4) doped with manganese ions are measured. It is established that the optical absorption spectra of yttrium aluminum borate single crystals doped with manganese ions are determined primarily by the contribution from the Mn4+ ions. The luminescence spectra of the YAl3(BO3)(4) single crystals doped with manganese exhibit narrow lines attributed to the Mn4+ ions and an extended multiband structure which is associated primarily with the contribution from the Mn2+ ions.
