A new method for determining the coordinate dependences of the pyroelectric current in ferroelectric materials

Abstract

A simplified method is proposed for determining the distribution of the effective pyroelectric coefficient over the depth of the sample. This method does not require a complex mathematical analysis involving solving ill-posed problems and makes it possible to determine the polarization state in the bulk of massive ferroelectric materials. The proposed method is tested with samples of the PZT commercial piezoceramic material.
