摘要：

Using a modified pseudospin model of NH3CH2COOH center dot H2PO3 ferroelectric taking into account the piezoelectric coupling with strains epsilon(i), epsilon(4), epsilon(5) and epsilon(6) within Glauber method in two-particle claster approximation, we have calculated components of dynamic dielectric permittivity tensor and relaxation times of the model. At the proper set of theory parameters, frequency and temperature dependences of the components of permittivity and temperature dependences of the relaxation times are studied. A satisfactory agreement of the theoretical results with experimental data for longitudinal permittivity is obtained.
