Abstract
Dynamic model of deformed quasi-one-dimensional ferroelectrics with hydrogen bonds is proposed. On the basis of this model within the two-particle cluster approximation with taking into account short-range and long-range interactions and strains εi and ε5 in the frames of Glauber method a dynamic dielectric permittivity of mechanically clamped crystal is calculated. Hydrostatic pressure effect on temperature and frequency dependences of the components of dynamic dielectric permittivity tensor of GPI ferroelectric is investigated.
