Abstract
The work is devoted to the theoretical investigation of the quasi-static magnetoelectric interaction in three-layer structures consisting of a piezoelectric and two magnetic layers with positive and negative magnetostriction. Using the system of elasto- and electrostatics equations for the piezoelectric and magnetostrictive phases, expressions for the electrical response of the structure in a magnetic field are obtained. The contributions from longitudinal and bending deformations are taken into account in value of ME interactions. It is shown that the use of an asymmetric three-layer asymmetric structure leads to an increase in the magnitude of the ME interaction by almost an order of magnitude compared to a two-layer structure. The dependences of the effect magnitude on the thickness of the third layer for the nickel/lead zirconate titanate/metglas structure are presented.
该研究致力于对由一个压电层和两个具有正负磁致伸缩性的磁层组成的三层结构中的准静态磁电相互作用进行理论研究。利用压电相和磁致伸缩相的弹性和静电方程系统，获得了结构在磁场中的电响应表达式。在计算 ME 相互作用值时，考虑了纵向和弯曲变形的贡献。结果表明，与双层结构相比，使用非对称三层非对称结构会导致 ME 相互作用的幅度增加近一个数量级。文中还介绍了镍/锆酸铅/钛酸铅/金属玻璃结构的效应大小与第三层厚度的关系。
