Magnetoelastic surface waves on the (110) plane of highly magnetostrictive cubic crystals

Abstract
Dispersion characterisitcs of magnetoelastic surface waves in highly magnetostrictive cubic crystals are calculated for different bias fields applied along the direction of propagation. Effects of anisotropy are taken into account. The surface waves are found to be leaky or nonleaky depending on the direction of propagation. Velocity of surface waves is calculated both before and after saturation of the magnetic moment. Although most of the velocity change with bias field occurs while the magnetization vector rotates from the easy direction to the field direction, the velocity changes by a few percent even after the moment saturates. Theoretical results are in good agreement with experiment.
