multiferroics -- magnetoelectric effect -- phase transition -- ferroelectricity
Аннотация: In this work, the magnetoelectric response in a series of Dy1−xHoxMnO3 crystals with substitution x from 0 to 0.4 was investigated. The measurement results showed that, as x increases, a decrease in both the polarization Pa and the magnitude of the susceptibility of the inverse magnetoelectric effect αba is observed. In addition, the field Hb increases, at which the Pc → Pa transition is observed, and the temperature range of the existence of the magnetoelectric response decreases. Thus, an increase in the substitution x suppresses the magnetoelectric effect in this series of compounds. The measurement results also indirectly indicate the prolongation of the Pa state and, consequently, of the magnetic state with a cycloid lying in the ab-plane by an external electric field Ea.

Аннотация: A new bismuth pyrostannate-based composite Bi2(Sn0.7Fe0.3)2O7-x/Bi2Fe4O9 (BSFO/BFO) has been obtained by the solid-state synthesis. Temperature dependences of the magnetic hysteresis and remanent magnetization and the nonlinear field dependence of the magnetization for the Bi2Fe4O9 antiferromagnet have been established. A temperature of the formation of canted sublattices in the antiferromagnet with the occurrence of a spontaneous moment in mullite has been determined. The mechanism of the electric polarization hysteresis and the temperature dependence of the remanent polarization have been established. It has been shown, that, below the Néel temperature, the dipole polarization is induced by a lone electron pair of bismuth ions. At T > TN, the migration polarization is caused by the charge carrier density at the chemical potential. A significant increase in the remanent magnetization of mullite in the bismuth pyrostannate matrix with oxygen vacancies over a value typical of polycrystalline mullite has been established. Remanent magnetization is explained in terms of ferron model.

    Coexistence of the electric polarization and conductive current in the bismuth–neodymium ferrite garnet films / S. S. Aplesnin, A. N. Masyugin, M. N. Volochaev, T. Ishibashi // J. Mater. Sci.

Аннотация: The Nd1Bi2Fe5O12/Nd2Bi1Fe4Ga1O12 polycrystalline films on the glass substrate and the Nd0.5Bi2.5Fe5O12 epitaxial films on the single-crystal gadolinium gallium garnet substrate have been investigated by impedance and dielectric spectroscopy. The inductive contribution to the impedance and two relaxation channels related to ferroelectric domains and migration polarization have been established. The magnetocapacitance and magnetoimpedance have been determined. The conductive and polarization currents and the phase difference between them for the films of two types have been determined. The critical temperatures of the polarization disappearance and hysteresis I–V have been found. A model of the polarization caused by the piezoelectric effect and flexoelectric interaction has been proposed. I–V hysteresis is explained by the presence of ferroelectric domains near the interface and is associated with the hysteresis of the electric polarization.

Soft modes -- low temperatures -- phonon-magnon interaction -- magnetic ordering -- huntite
Аннотация: The condensation of two soft modes has been found when studying the Raman spectra of the solid solution HoFe2.5Ga0.5(BO3)4 in the temperature range from 7 to 350 K. The first high-temperature soft mode is associated with the structural phase transition from the R32 phase to the P3121 phase. The second soft mode is related to the reveal of the phonon-magnon interaction during magnetic ordering in the crystal. The temperatures of the structural phase transition T1 = 266 K and the magnetic phase transition T2 = 28 K are established. Experimentally interaction between the structural phase transition order parameter fluctuations and the magnetic order parameter fluctuations was found.

Fluorides -- Raman spectra -- lattice disordering
Аннотация: In order to clarify ordering mechanisms of ferroic phase transitions in double fluoride salts (NH4)3SnF7, (NH4)3GeF7 and (NH4)3TiF7, their Raman scattering spectra have been studied in wide ranges of frequencies (20–3400 cm−1) and temperatures (8–410 K). Substitution of the central ion in the octahedron groups was found to change not only the phase transition types and sequences, but to modify the types of structural disorder as well, which is a special feature of these high-symmetry fluoride crystals.

    Pressure-Induced Structural Transition to the Polar Phase in GdFe3(BO3)4 / I. S. Lyubutin [et al.] // Cryst. Growth Des. - 2019. - Vol. 19, Is. 12. - P. 6935-6944, DOI 10.1021/acs.cgd.9b00609. - Cited References: 39. - The authors express their deep gratitude to Prof. S. G. Ovchinnikov for initiating this work and fruitful discussions. These studies were performed with the support of the Ministry of Science and Higher Education within the State assignment FSRC "Crystallography and Photonics" RAS in part for the synchrotron Mössbauer measurements. Support from RFBR Grant No. 17-02-00766 in part for the Raman spectroscopy measurements and from No. 18-02-00696 in part for the theoretical calculations is also acknowledged. For preparation and tests of high-pressure cells, (39) the facilities of Center for Collective Use “Accelerator Center for Neutron Research of the Structure of Substance and Nuclear Medicine” of the INR RAS were used. . - ISSN 1528-7483

Boron -- Crystal lattices -- Ferroelectricity -- Ions -- Iron compounds
Аннотация: The GdFe3(BO3)4 crystal has attracted great interest as a magnetic-field-induced multiferroic. In this paper, we show that the multiferroic properties in this crystal can be induced by high pressure. At high pressures up to 50 GPa, created in diamond anvil cells, the structural and vibrational (phonon) properties of the GdFe3(BO3)4 crystal were studied. The structural phase transition was detected at about 23–25 GPa by Raman and synchrotron Mössbauer (NFS) spectroscopy. First-principle calculations of the crystal lattice dynamics at pressures below and above the structural transition were carried out. It was established that at pressures above the structural transition, the space group R32 of GdFe3(BO3)4 is changed to the polar space group R3, and the crystal becomes a ferroelectric. At the R32 → R3 transition, the displacement of the boron ion B(2) and oxygen O results in the formation of boron–oxygen B(2)O4 tetrahedrons instead of the plane BO3 triangles. Meanwhile, the triangle oxygen environment of boron in the site B(1) remains unchanged. The nearest environment of the gadolinium ion also changes significantly. Instead of six oxygen ions in the R32 phase, the nearest surroundings of Gd in the R3 phase consist of nine oxygen ions forming a complex polyhedron. A large hysteresis of the transition indicates that this crystal remains a ferroelectric with a decrease in pressure to about ambient pressure.

Аннотация: Vibrational, polarization, magnetic, and electronic properties of double perovskites CaMnTi2O6 and CaFeTi2O6 with a rare type of “column” ordering of divalent metal cations have been calculated based on the density functional theory. Analysis of the crystal lattice dynamics for paraelectric phase P42/nmc of both compounds has revealed that ferroelectric instability exists only in CaMnTi2O6. It is found that the structure distortion of the paraphrase of CaMnTi2O6 in the eigenvector of the unstable polar mode leads to a structure with the P42/nmc space group. The calculated spontaneous polarization for the ferroelectric phase of CaMnTi2O6 is Ps = 25 μC/cm2. The spin-polarization calculations have shown that the ground state is ferromagnetic in the CaFeTi2O6 crystal and antiferromagnetic in the CaMnTi2O6 crystal. The exchange interaction constants have been calculated using the Heisenberg model and the mean field approximation; the phase transition temperature for each compound has been estimated.

Аннотация: The Raman spectra of Rb2KLuF6 elpasolite crystal have been studied in a wide temperature range, including two phase transitions: from the cubic phase to the tetragonal phase and then to the monoclinic phase. The results of an analysis of the temperature dependences of the parameters of spectral lines are in good agreement with the thermodynamic data on the phase transitions. The analysis of Raman spectra shows that the transition from cubic to tetragonal phase is a second-order transition and the transition from the tetragonal to the monoclinic phase is a weak first-order transition.
