Abstract

ABSTRACT Reversible electrostrictive effect in ferroelectrics of double-well free energy is modeled using the Devonshire theory. The idea is developed that in tetrogonal phase 90° turnings of dipoles from four poling axises, isoenergetic minima, perpendicular to electrical field to the direction of electrical field cause electrostriction. Numerical simulation results exhibit that the exchanging coupling coefficient between dipoles results in a butterfly shaped electrostriction loop. Influences of temperature and the two parameters of materials on shape of electrostriction loop are discussed, and an empirical experimental law, about magnitude of electrostriction with the Curie constant, is confirmed.
二阶相变铁电体的电致伸缩效应研究
利用Devonshire理论对双阱自由能铁电体中的可逆电伸缩效应进行了建模。提出了在四角形相位中,偶极子从垂直于电场的四个极轴(等能极小值)向电场方向旋转90°引起电致伸缩的思想。数值模拟结果表明,偶极子之间的交换耦合系数导致了蝴蝶形的电致伸缩环。讨论了温度和材料的两个参数对电致伸缩回路形状的影响,并证实了电致伸缩量随居里常数变化的经验实验规律。

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.
