摘要

摘要在很宽的开关场频率范围内研究了单轴硫酸甘氨酸（TGS）铁电介质的介电滞回。实验结果将矫顽力场对开关频率的依赖性与科尔莫戈罗夫-阿夫拉米畴开关模型和畴成核模型进行了比较。结果表明，这两种切换模型与实验结果相当吻合，而且切换畴运动的特征会随着切换场频率的变化而改变。

On the Dielectric Hysteresis Loops of a Uniaxial Ferroelectric

Abstract

The dielectric hysteresis loops of a uniaxial triglycine sulfate (TGS) ferroelectric have been studied in a wide range of switching field frequencies. The experimental dependence of the coercive field on the switching frequency is compared with the Kolmogorov–Avrami domain switching model and the domain nucleation model. It is shown that both switching models agree reasonably well with the experiment and that the character of switched domain motion changes with a change in the switching field frequency.
