Paper Title:
Dipole Cluster State and Dielectric Relaxation in Relaxor Ferroelectrics
  Abstract

The Ginzburg-Landau theory on ferroelectrics with random field induced by dipole defects is studied using Monte Carlo simulation in order to investigate the possible dipole clustering and freezing behaviors as well as the dielectric relaxation of relaxor ferroelectrics. The dipole clustering above the transition temperature and the cluster-freezing far below this temperature are identified. The intrinsic correspondence between dipole-clustering/freezing and the multi-peaked time-domain distribution of dielectric relaxation is established.
