Electrocaloric and barocaloric effects in CsHPO ferroelectric
A. S. Vdovych, R. R. Levitskii, I. R. Zachek
To investigate the caloric effects in the CsHPO ferroelectric, a modified pseudospin model of this crystal is used, which takes into account the dependence of the parameter…
Effect of hydrostatic pressure on dynamic dielectric characteristics of CsHPO ferroelectric
A. S. Vdovych, I. R. Zachek, R. R. Levitskii
Based on the pseudospin model of the deformed CsHPO crystal within the Glauber method, the equation for the time-dependent mean value of the pseudospin is obtained, which i…
Effect of hydrostatic pressure and longitudinal electric field on phase transitions and thermodynamic characteristics of quasione-dimensional CsHPO ferroelectric
A. S. Vdovych, I. R. Zachek, R. R. Levitskii
We propose a two-sublattice proton ordering model for the quasione-dimensional CsHPO ferroelectric with hydrogen bonds, which takes into account linear on lattice strains $…
Reference approach in theory of pseudospin systems
R. R. Levitskii, S. I. Sorokov, O. R. Baran
For theoretical description of pseudospin systems with essential short-range and long-range interactions we use the method based on calculations of the free energy functional with…
Pair correlation functions of the Ising type model with spin 1 within two-particle cluster approximation
O. R. Baran, R. R. Levitskii
The Blume-Emery-Griffiths model on hypercubic lattices within the two-particle cluster approximation is investigated. The expressions for the pair correlation functions in …
Phase diagrams of spin-1 Ising model with bilinear and quadrupolar interactions under magnetic field. Two-particle cluster approximation
R. R. Levitskii, O. R. Barana, B. M. Lisnii
The spin-1 Ising model with bilinear and quadrupolar short-range interactions under magnetic field is investigated within the two-particle cluster approximation. It is shown that f…
