Magnetoelectric and magnetostriction characteristics of symmetric three layered structures of nickel - lead zirconate titanate – nickel and permendure – lead zirconate titanate – permendure

The magnetoelectric and magnetostriction characteristics of the symmetric three-layered structures are presented. The composite structures were formed like sandwich structures with a piezoelectric layer between two identical magnetostrictive layers using epoxy adhesive. An analytical expression for magnetoelectric voltage coefficient in terms of parameters for magnetostrictive and piezoelectric subsystems is presented. On the basis of this expression determination of magnetostriction characteristics via magnetoelectric response was offered. This procedure was tested for these three layered structures using the field dependences of the magnetoelectric response. The magnetostrictive characteristics obtained are in good agreement with results, obtained by other methods.
