Magnetoelectric Effect in the Bidomain Lithium Niobate/Nickel/Metglas Gradient Structure

Abstract

The paper describes the magnetoelectric (ME) effect in a gradient laminate structure consisting of a LiNbO 3 /Ni/metglas multilayer based on a bidomain lithium niobate single crystal with a Y + 128° cut. The main purpose of the work is to obtain a self‐biased structure. A theoretical and experimental study is conducted to determine the optimal thickness of the Ni film for creating such a structure. The application of self‐biased structures based on gradient bidomain crystals in ME devices can significantly reduce their weight and dimensions as well as improve their electrical characteristics.
