Automatic system for determination of dielectric hysteresis loop parameters

Abstract

Research works were focused on design and implementation of based on Sawyer-Tower measurement set, computer system, capable to record parameters of dielectric hysteresis loop of non-linear dielectrics. This measurement system makes possible automation and simplification of measurements process and preliminary data processing. Exemplary measurements of temperature characteristics of coercive field and spontaneous polarization of ferroelectric single crystals are also presented in the paper.
