Abstract: 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. It is shown that the relaxation processes depend on the localization of lead oxide in the bulk of the film.
Keywords: thin films of lead zirconate-titanate, dielectric permeability, relaxation time, crystallization temperature, lead oxide.
