Заглавие : Structural features associated with multiferroic behavior in the RX3(BO3)4 system
Место публикации : J. Phys. Condens. Matter. - 2019. - Vol. 31, Is. 50. - Ст.505704. - ISSN 09538984 (ISSN), DOI 10.1088/1361-648X/ab415f

Аннотация: The magnetoelectric effect in the RX3(BO3)4 system (R = Ho, Eu, Sm, Nd, Gd; X = Fe, Al) varies significantly with the cation R despite very similar structural arrangements. Our structural studies reveal a symmetry reducing tilting of the BO3 planes and of the FeO6 polyhedra in the systems exhibiting low magnetic field induced electric polarization. Neutron scattering measurements reveal a lack of magnetic ordering indicating the primary importance of the atomic structure in the multiferroic behavior of this system.

Место публикации : J. Alloys Compd. - 2019. - Vol. 806. - P.1047-1051. - ISSN 09258388 (ISSN), DOI 10.1016/j.jallcom.2019.07.273

Аннотация: In this study, the conventional and inverse barocaloric effects (BCE) in ferroelectric NH4HSO4 are reported. Maximum extensive and intensive BCE near order–disorder phase transition can be achieved at low pressure p≤0.1 GPa. Large thermal expansion of the crystal lattice plays a very important role in the developing conventional BCE and conversation between BCE of different sign in the narrow temperature range.

Аннотация: Results are presented from studying the X-ray diffraction, heat capacities, dielectric permittivities, and coefficients of the volumetric thermal expansion of composite materials obtained by embedding of Rb2ZnCl4 salt into the porous matrices of borosilicate glass with average pore diameters of 46 and 320 nm in the temperature range of 120–350 K. The temperatures of transitions to the incommensurate and ferroelectric phases are determined, along with the freezing temperature of the mobility of domain boundaries in Rb2ZnCl4 particles. A substantial increase in their Curie temperature is observed.

Аннотация: The ferroelectric properties of bismuth pyrostannate Bi2(Sn0.85Cr0.15)2O7 in the high-temperature region are established. The linear thermal expansion coefficient, electrical resistance, impedance, I−V characteristics, capacitance, loss-angle tangent, charge, and thermopower of the investigated material are measured in the temperature range of 300−700 K at frequencies of 102−106 Hz. Anomalies of the thermal expansion coefficient and hodograph spectrum variation in the region of polymorphic phase transitions are observed. The high resistance and change of the hopping conductivity for the tunnel-emission are found. The hysteresis in the electric field dependence of polarization is established. The change in the thermopower sign with temperature is revealed. The obtained experimental data are explained in the framework of the model of migration polarization by charged chromium ions.

Аннотация: The effect of restricted geometry on specific heat capacity and thermal expansion of the triglycine sulfate (TGS)–borosilicate glass composites have been studied first. A decrease in the entropy and temperature of the P21 ↔ P21/m phase transition in the TGS component with decreasing the glass matrix pore diameter at the invariable specific heat and thermal expansion coefficient has been observed. The estimates are indicative of the minor effect of internal pressure on the TGS pressure coefficient dTC/dp in the composites.

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: In SrxBa1-xNb2O6 crystals (x = 0.33, 0.5, 0.61, and 0.75), temperature dependences of spontaneous polarization, strain, elastic modules, and second harmonic generation (SHG) signal are compared. It is revealed that SHG describes the temperature dependences of dipole moments in polar nanoregions in paraelectric phase. In the vicinity of the phase transition in paraelectric phase, SHG reflects the temperature behavior of relatively large and long-lived polar asymmetric regions as indicated by the presence of the intermediate temperature range on the temperature dependence of this nonlinear response.

Заглавие : Features of the behavior of the barocaloric effect near ferroelectric phase transition close to the tricritical point
Место публикации : Crystals. - 2020. - Vol. 10, Is. 1. - Ст.51. - ISSN 2073-4352, DOI 10.3390/cryst10010051

Аннотация: A detailed study of the effect of temperature and pressure on heat capacity, entropy and hysteresis phenomena near the ferroelectric phase transition in ammonium sulfate (AS) was performed. An analysis of experimental results within the framework of the phenomenological theory showed that taking into account the temperature-dependent part of the anomalous entropy leads to a significant increase in the barocaloric effect (BCE). The maximum values of extensive and intensive BCE near the tricritical point are outstanding: ΔSmaxBCE≈85 J/kgK, ΔTmaxAD≈12 K and can be achieved at low pressure ∼0.5 GPa.

Аннотация: The role of anisotropy of the thermal expansion in formation of piezocaloric effect (PCE) near ferroelectric phase transitions in NH4HSO4 was studied. Strong difference in linear baric coefficients and as a result in intensive and extensive PCE associated with the different crystallographic axes was found. PCE giving the main contribution to the barocaloric effect were determined at both phase transitions. Rather strong effect of the lattice dilatation on the tuning of PCE was observed. Comparative analysis of PCE at the phase transitions in different materials showed that NH4HSO4 can be considered as a promising solid-state refrigerant. A hypothetical cooling cycle based on alternate using uniaxial pressure along two axes was considered.

Аннотация: We report the influence of anisotropy and texture on elasto(ElCE)- and baro(BCE)-caloric effects in single-crystal and ceramic (NH4)2SO4. Inverse extensive and intensive ElCE in ceramics, (ΔSElCE)cer = 87 J/kg·K; ΔTAD = - 11.6 K), as well as in a single crystal along the ferroelectric axis a, (ΔSElCE)a = 115 J/kg·K; (ΔTAD)a = - 16 K, significantly exceed BCE, ΔSBCE = 75 J/kg·K; ΔTAD = - 9.8 K, even at low pressure ~ 0.3 GPa. Caloric parameters of ammonium sulphate are comparable with those for promising solid-state refrigerants.

Заглавие : Size effect on sensitivity to external pressure and caloric effects in TGS: Ceramics and nanocomposites
Место публикации : Mater. Today Commun. - 2020. - Vol. 25. - Ст.101463. - ISSN 23524928 (ISSN), DOI 10.1016/j.mtcomm.2020.101463

Аннотация: Experimental study of temperature-pressure phase diagrams revealed a slight difference in the sensitivity to hydrostatic pressure of triglycine sulfate (TGS) as a bulk (single crystal, ceramics), and nanoparticles embedded in porous glass (TGS + PG). An analysis of the pressure sensitivity, dT0/p and dT0/dσ, and entropies of the P21 ↔ P21/m phase transition showed the closeness of the barocaloric parameters in various materials under study. Due to the strong anisotropy of thermal expansion, the piezocaloric effect under pressure along the axis c exceeds the barocaloric effect in single-crystal TGS. The reasons for the strong reduction in the electrocaloric effect in the ferroelectric component of nanocomposites compared with a single-crystal are discussed.

Аннотация: Raman spectra in barium titanate powder under non-hydrostatic pressures are presented. The relationship between the pressure (up to 11 GPa) and the shift and the width of E(TO)-phonon line has been established. It has been found that under the action of uniaxial pressure a new Raman peak arises in the vicinity of 100 cm−1. It is shown that the Raman shift and width of both peaks increase depending on the applied pressure. These Raman lines broadening may be associated with an increase of the concentration of defect states in the volume of the sample.
