A random-field model for ferroelectric domain dynamics: analysis by stretched exponential functions
Polarization reversal and domain dynamics have been investigated in 0.7Pb(Mg/sub 1/3/Nb/sub 2/3/)O/sub 3/-0.3PbTiO/sub 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.
