使用电流瞬变方法研究了 0.7Pb(Mg1/3Nb2/3) O3–0.3PbTiO3 的极化反转和磁畴动力学。根据所施加的电场进行研究。瞬态动力学已被建模为随机场附近异质成核的状态方程。具有反向极化的极性簇的成核发生在随机淬火缺陷附近的施加场下。
Polarization reversal and domain dynamics have been investigated in 0.7Pb(Mg1/3Nb2/3) O3–0.3PbTiO3 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 an equation of state for heterogeneous 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.
