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 $…
