ABSTRACT:
A magnetoelastic wave device comprising a substrate, a magnetostrictive film formed over the substrate, a wave generating section, a wave receiving section, and a modulation magnetic field generating section. The magnetostrictive film has an axis of easy magnetization which is substantially <uv0> axis and extends parallel to the major surfaces of the magnetostrictive film.
