Effect of hydrostatic pressure and longitudinal electric field on phase transitions and thermodynamic characteristics of quasione-dimensional CsH $_{2}$ PO $_{4}$ ferroelectric

A. S. Vdovych, I. R. Zachek, R. R. Levitskii

We propose a two-sublattice proton ordering model for the quasione-dimensional CsH $_{2}$ PO $_{4}$ ferroelectric with hydrogen bonds, which takes into account linear on lattice strains $…

Piezocaloric and multicaloric effect in the KH2PO4 type ferroelectrics

A. S. Vdovych, A. P. Moina, R. R. Levitskii +1

Using the proton ordering model modified by taking into account the dependence of the dipole moments on the order parameter [Vdovych et al, 2014], we explore the piezocaloric and m…
