摘要

Computer simulation of repolarization and inverse piezoeffect is realized by Monte-Carlo method in polymer ferroelectric materials, observed in AC electric field with different frequencies and amplitudes. For describing the interactions between the segments of polymer chains, Lennard-Jones potential was used with additional term describing exchange short-range orientational interactions. We investigate the influence of temperature and parameters of external electric field on the hysteresis curve area, which determines the absorption coefficient. It is shown that for ferroelectric systems there is a frequency of the external field, which accounts for the maximum absorptivity.
