Abstract

A magnetic piezoelectric composite adjusts magnetic anisotropy strength in a bimetallic member and includes: a piezoelectric layer to produce a strain in response to receipt of a strain voltage; and the bimetallic member disposed on the piezoelectric layer, the bimetallic member including: a plurality of metal layers, such that a second metal layer is interposed between a pair of first metal layers, the bimetallic member being ferromagnetic; and a magnetic anisotropy strength that changes in response to receipt of the strain from the piezoelectric layer.
