Abstract
A theory describing polarization reversal in BaTiO3 c-domain crystals based on observed time and field dependence of polarization P=f(E,t) is presented, and the activation field α as well as mobility μ are related to the constants appearing in the basic differential equation. The theory gives time and field dependence of the switching current at constant temperature. Although the theory does not imply restriction on the applied field E(t), results are given only for pulsed and sinusoidal fields. The effect of skin properties on the bulk crystal has been considered. Dependence of coercive field on applied field and frequency are readily obtained. Switching resistance is calculated.
