D. Viehland et Jf. Li, Kinetics of polarization reversal in 0.7Pb(Mg1/3Nb2/3)O-3-0.3PbTiO(3): Heterogeneous nucleation in the vicinity of quenched random fields, J APPL PHYS, 90(6), 2001, pp. 2995-3003
Polarization reversal and domain dynamics have been investigated in 0.7Pb(M
g1/3Nb2/3) O-3-0.3PbTiO(3) using a method of current transients. Investigat
ions were performed as a function of applied electric field. The kinetics o
f the transients have been modeled to an equation of state for heterogeneou
s nucleation in the vicinity of random fields. Nucleation of polar clusters
with a reversed polarization occurs under applied field in the vicinity of
randomly quenched defects. (C) 2001 American Institute of Physics.
