摘要：
Polarization reversal and domain dynamics have been investigated in 0.7Pb(Mg1/3Nb2/3)O-3-0.3PbTiO(3) using a method of current transients. Investigations were performed as a function of applied electric field. The kinetics of the transients have been modeled to a stretched exponential type function. We believe that nucleation of polar clusters with a reversed polarization occurs under applied field in the vicinity of randomly quenched defects.
