Statistical theory of thermodynamic and dynamic properties of the RbHSO_{4} ferroelectrics
Within the modified four-sublattice model of RbHSO_{4} with taking into account the piezoelectric coupling to the strains ε_{i}, ε_{4}, ε_{5}, and ε_{6}, the polarization components, static and dynamic dielectric permittivity of clamped and free crystal are calculated in the mean field approximation...

| Summary: | Within the modified four-sublattice model of RbHSO_{4} with taking into account the piezoelectric coupling to the strains ε_{i}, ε_{4}, ε_{5}, and ε_{6}, the polarization components, static and dynamic dielectric permittivity of clamped and free crystal are calculated in the mean field approximation. At the proper choice of the values of the theory parameters, a satisfactory quantitative description of the available experimental data is obtained. |
