Аннотация:
Raman spectra of Ho1-xNdxFe(BO3)4 (x=1, 0.75, 0.5, 0.25) have been studied in temperature range 10-400K. Two compositions (x=1, x=0.75) demonstrate structural phase transition with soft mode restoration. The addition of Nd atoms increases interatomic spacing and decreases the temperature of structural phase transition. The solid solutions (x=0.75, 0.5, 0.25) demonstrate the emergence of the peaks corresponding to magnetoelastic interaction below Neel temperature. The order parameter of the magnetic phase transition has been determined. The equal concentrations of holmium and neodymium atoms prevent magnon soft modes condensation caused by exchange interactions in Fe-O-Fe chains are observed. Calculations confirm the data obtained in the experiment.

Аннотация:
We present the results of studies of thermal expansion, heat capacity, permittivity, polarization and the influence of different thermal conditions on the intensive electrocaloric effect (ECE), ΔTAD, in a commercial multilayer capacitor based on doped BaTiO3. Investigations in a wide temperature range revealed one anomaly in the behavior of the physical properties at about 290K characteristic for the relaxors. Direct measurements showed a high reversibility of ECE under equilibrium thermal conditions. Good agreement was found between the values of ΔTAD determined by direct and indirect measurements at the electric field up to 15.4 kV/cm. Quasi-isothermal conditions lead, firstly, to decrease of large ΔTAD ≈0.94K obtained in adiabatic conditions under E = 308 kV/cm to 0.87 K, and, secondly, the appearance of a difference between the values of ΔTON and ΔTOFF determined when the electric field is applied and removed. Using this phenomenon and changing the frequency of the periodic electric field, E = 15.4 kV/cm, the effect of cooling was obtained equal to [(ΔTON + ΔT OFF)/2]max = -0,032 K. The results obtained are useful for further development of the electrocaloric refrigeration technique without thermal switches.

Аннотация:
A comparative analysis of the copper and iron ions bonds exchange energies was conducted for various variants of orderings and distributions of iron ions among crystallographic positions in ludwigite Cu2FeBO5. Analysis showed that the exchange bonds of iron ions play a key role in the formation of magnetic order. The magnetic ordering strongly depends on the distribution of iron ions among the positions. In the case when the Fe3+ is in the same position as in Fe3BO5, the most favorable magnetic structure is similar to the magnetic structure of ludwigite Fe3BO5. In other cases, the type of magnetic ordering is different.

Аннотация:
A new polymorphic modification of lanthanum sulfate was obtained by thermal dehydration of the respective nonahydrate. According to powder X-ray diffraction, it was established that β-La2(SO4)3 crystallized in the C2/c space group of the monoclinic system with the KTh2(PO4)3 structure type (a = 17.6923(9), b = 6.9102(4), c = 8.3990(5) Å, β = 100.321(3)°, and V = 1010.22(9) Å3). Temperature dependency studies of the unit cell parameters indicated almost zero expansion along the a direction in the temperature range of 300–450 K. Presumably, this occurred due to stretching of the [LaO9]n chains along the c direction, which occurred without a significant alteration in the layer thickness over the a direction. A systematic study of the formation and destruction processes of the lanthanum sulfates under heating was carried out. In particular, the decisive impact of the chemical composition and formation energy of compounds on the thermodynamic and kinetic parameters of the processes was established. DFT calculations showed β-La2(SO4)3 to be a dielectric material with a bandgap of more than 6.4 eV. The processing of β-La2(SO4)3 with the Kubelka–Munk function exhibited low values below 6.4 eV, which indicated a fundamental absorption edge above this energy that was consistent with LDA calculations. The Raman and infrared measurements of β-La2(SO4)3 were in accordance with the calculated spectra, indicating that the obtained crystal parameters represented a reliable structure.

The physical properties of the NiB4O7 and CoB4O7 tetraborate compounds in three structural modifications with the sp. gr. Pbca, Cmcm, and P6522 have been calculated using the density functional theory in the VASP software package. The pressure dependences of the enthalpy of the compounds in the investigated structural modifications have been calculated.

Low frequency Raman spectra of (Pb0.97La0.02)(Zr0.864Sn0.04Ti0.096)O3 ceramic samples have been studied near cubic to antiferroelectric phase transition at about 200 °C. A set of low frequency soft modes were observed restoring below the transition point, in addition to the known one above 100cm-1. These modes show strong damping anomalies at the transition point that supposes considerable intermode interactions via dampings. © 2019 The Author(s).

The ludwigite Ni5Ge(BO5)2 belongs to a family of oxyborates which have low-dimensional subunits in the form of three-leg ladders unit structure. This material was studied by magnetic and thermodynamic measurements. Ni5Ge(BO5)2 does not show full long-range magnetic order, but one goes into a partial ordering or spin-glass state at 87 K. The superexchange interactions were calculated in the framework of a simple indirect coupling model. Different models of magnetic structure of Ni5Ge(BO5)2 and its unique magnetic behaviour was discussed. © 2015 Elsevier B.V.

Ni3B2O6 and Co3B2O6 single crystals
Аннотация:
Orthorhombic Me3B2O6 (Me = Co, Ni) single crystals of the kotoite family are grown from the fluxes based on a mixture of bismuth trimolybdate and sodium oxide upon spontaneous nucleation. The field and temperature dependences of magnetization of the single crystals with the magnetic field oriented along the principal crystallographic directions are obtained. Unlike Ni3B2O6, Co3B2O6 exhibits strong anisotropy of the magnetic properties. At the temperature T = 10 K, the magnetization curves of Co3B2O6 reveal an anomaly attributed to the spin-reorientation transition. Strong anisotropy of the magnetic properties of Co3B2O6 is also confirmed by the calculation of the exchange interactions within a simple indirect coupling model.
