Paper Abstract

In the paper we present discussion of two methods of measurements and determination of spontaneous polarization and coercive field for materials showing dielectric hysteresis loop. The first method is based on the idea of Sawyer-Tower bridge (S-T), the second method is based on Diamand-Dreck-Pepinsky bridge. Based on available literature and previous experiences we constructed a computer measurement system for research over the shape of dielectric hysteresis loop. Using the above mentioned equipment we can measure spontaneous polarization (Ps), coercive field (Ec), and also shift field (Ep) in the case of dielectrics showing asymmetrical loop.
