Abstract The theory of the direct magnetoelectric effect in a bilayer ferromagnetic—piezoelectric structure is presented with the exact consideration for electric fields, inhomogeneous over the thickness of the piezoelectric layer. The solution of the motion equations for a piezoelectric and ferromagnetic medium made it possible to numerically-analytically calculate the dependence of the natural frequency of mechanical oscillations on structure parameters and frequency dependence of the magnetoelectric coupling coefficient. Consideration of the structure dissipative properties makes it possible to estimate the maximum value of the magnetoelectric coupling coefficient.

耗散特性对双层膜中磁电系数的影响

摘要 提出了双层铁磁 - 压电结构中的直接磁电效应理论，并准确考虑了电场，在压电层的厚度上是不均匀的。压电和铁磁介质运动方程的解使得可以数值分析计算机械振荡的固有频率对结构参数的依赖性和磁电耦合系数的频率依赖性。考虑结构耗散特性使得估计磁电耦合系数的最大值成为可能。
