Abstract

Dielectric properties of epitaxial relaxor ferroelectric thin-film heterostructures were experimentally studied in a broad range of temperature, frequency, and amplitude of ac-field. Contribution of the film-electrode interfaces to the properties of the heterostructures was evaluated and the true properties of the films were reconstructed and analyzed. In the films, the Vögel-Fulcher relationship, deviation from Curie-Weiss behavior, temperature evolution of local order parameter, relaxation-time spectrum, and dielectric nonlinearity were found to be essentially similar to those in bulk relaxor ferroelectrics.
