Abstract

The work is devoted theoretical and experimental studies of a magnetoelectric gyrator, consisting of an inductor coil, inside which there is a magnetoelectric heterostructure, which is a mechanically connected piezoelectric layer and two magnetic layers. Using the system of equations of elasto- and electrodynamics for the piezoelectric and magnetostrictive phases, expressions are obtained for the current/voltage conversion coefficient of the gyrator in terms of the phase parameters of the heterostructure. An experimental sample of a gyrator based on the Metglas/PZT/Metglas heterostructure was fabricated. Theoretically calculated and experimentally studied the frequency and load characteristics of the gyrator. It is shown that theoretical calculations are in good agreement with experimental data. Recommendations for the creation of gyrators with the highest current/voltage conversion efficiency are presented.

三层对称结构的磁电陀螺仪:理论和实验

本文对一种磁电旋转器进行了理论和实验研究，该旋转器由电感线圈组成，电感线圈内部有一个磁电异质结构，由机械连接的压电层和两个磁性层组成。利用压电相和磁致伸缩相的弹性动力学和电动力学方程组，得到了旋转器的电流/电压转换系数与异质结构相参数的表达式。制作了基于metglass /PZT/ metglass异质结构的旋转器实验样品。对旋转器的频率特性和载荷特性进行了理论计算和实验研究。结果表明，理论计算与实验数据吻合较好。提出了创造具有最高电流/电压转换效率的旋转器的建议。
