摘要：

Investigations of the frequency dependence of the P-E (polarization versus field) and epsilon-E (strain versus field) behavior have been performed on soft 0.7Pb(Mg1/3Nb2/3)O-3-0.3PbTiO(3) polycrystalline ferroelectrics at various maximum field strengths below and above that of the coercive field (E-c). For E < E-c, a strong relaxational polarization was observed. At low frequencies, in this field range, P-E curves indicative of polarization switching were observed with an apparent remanence, however at higher frequencies near-linear P-E behavior was found.
