【 摘 要 】

Within the modified four-sublattice pseudospin model of deformed RbHSO$_{4}$ ferroelectrics, using the Glauber method and the mean field approximation, we calculate the dynamic dielectric permittivity of a mechanically clamped crystal and explore its dependence on hydrostatic pressure in wide temperature and frequency ranges. A satisfactory quantitative agreement with the experimental data is obtained.
