Influence of External Pressures of Different Symmetry on the Phase Transitions and Thermodynamic of the RbHSO4 Ferroelectrics
Journal Title: Фізика і хімія твердого тіла - Year 2015, Vol 16, Issue 2
Abstract
We use the four-sublattice model of the RbHSO4 crystal modified by taking into account the piezoelectric coupling to the strains ei, ej . Within the mean field approximation we calculate the components of the polarization vector and static dielectric permittivity tensor of mechanically clamped and free crystals, as well as their piezoelectric characteristics. We study the influence of hydrostatic pressure ph and uniaxial stresses pi on the phase transition and physical characteristics of the crystal. A good quantitative description of the experimental data is obtained.
