The paper presents the results of a study of relaxation of the dielectric permittivities in constant electric fields upon switching the polarization of thin films of lead zirconate-titanate. crystallized at different annealing temperatures. It is shown that the relaxation processes are characterized by at least three relaxation times which depend on the crystallization temperature.
