摘要

本文提出了一种通过电场表征铁电体极化的简单方法。这种方法使我们不仅可以像经典模型那样使用实验电场极化曲线,而且可以使用铁电体的物理状态。该方法基于费米-狄拉克分布,从8个测得的两种铁电材料的P-E曲线中,很好地重复了理论极化电场曲线的实验路径。同时,通过数学途径解释了物理状态对铁电磁滞回线的影响。

Calculation ferroelectric hysteresis loop via an explicit function
ABSTRACT In this paper, a very simple methodology to characterize the polarization of ferroelectrics via electrical field is proposed. This methodology allows us to use not only experimental electrical field-polarization curve as classical models do, but also physical status of ferroelectrics. The methodology is based on the use of Fermi-Dirac distribution, from eight measured P–E curves of two ferroelectrics materials, the theoretical polarization-electrical field curve repeat experimental path very well. Meanwhile, the effects of physical status on ferroelectric hysteresis loop are explained through mathematical route.

期刊介绍: Ferroelectrics Letters is a separately published section of the international journal Ferroelectrics. Both sections publish theoretical, experimental and applied papers on ferroelectrics and related materials, including ferroelastics, ferroelectric ferromagnetics, electrooptics, piezoelectrics, pyroelectrics, nonlinear dielectrics, polymers and liquid crystals. Ferroelectrics Letters permits the rapid publication of important, quality, short original papers on the theory, synthesis, properties and applications of ferroelectrics and related materials.
