　　The presence of domain wall and wall motion may significantly contribute to the dielectric response of a ferroelectric through the significantly larger intrinsic dielectric constant at the domain walls as well as the domain all motion.In this work,we employ phase-field modeling to study the domain wall motion and dielectric responses of multi-axial ferroelectrics Pb(Zr0.2,Ti0.8)O3(PZT)thin films.
