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 tin 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 ~ analyzed via numerical results.
