Peculiarities of the process of switching polarization in polycrystalline thin films of lead zirconate-titanate
The paper presents the results of a Razor Blades 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 wh
