Analysis of Bulk Second-Order Ferroelectric Switching in Oscillatory Dynamical System

Abstract

A detailed analysis of polarization reversal in bulk for second-order ferroelectric (FE) phase transition material in the framework of the Landau model is presented. We focus on the changes of polarization P and its switching current j with respect to time t in the presence of an external electric field E.By using the Landau-Khalatnikov (L-K) equation of motion, the dynamics of the FE material based on the oscillatory system is assumed. The changes in polarization and switching with respect to the different value of and temperature are Tr analyzed via numerical results.
