摘要：

The p-e hysteresis loop near the morphotropic phase boundary in the perovskite-type oxide solid solution system is discussed on the basis of a Landau-type free energy function. It was found that the coercive field in the p-e hysteresis loop decreases upon approaching the morphotropic phase boundary and vanishes at the morphotropic phase boundary, because of the instability in the direction perpendicular to the polarization.
