Abstract
The theory of the magnetoelectric effect in a bilayer magnetostrictive-piezoelectric structure magnetic-piezoelectric in the low-frequency region of the spectrum is presented. Based on the solution of the equations of the elastic theory and electrostatics, a simple expression for the magnetoelectric voltage coefficient in terms of the physical parameters of the material and the geometric characteristic of the structure is obtained. The contribution to the magnitude of the effect due to bending deformations and planar deformations is considered. It is shown that the contribution from planar deformations to the magnitude of the effect significantly exceeds the contribution from bending deformations. The calculation results for the structures nickel – PZT, permendur – PZT, Terfenol-D – PZT, Metglas – PZT are presented.
