Abstract
It is known [1] that shear surface waves cannot propagate in elastic media in the absence of a magnetic field, and Rayleigh surface waves always exist under the indicated conditions. It is known, also, in a magnetosoft ferromagnetic half-space (which material does not possess by magnetostrictive properties) when propagates Rayleigh waves, as a result, shear surface wave generates in presence of inclined to the motion surface magnetic field [2]. In this paper it is established that Rayleigh and shear surface waves can propagate independently of each other in a magnetostrictive half-space, if there is a magnetic field perpendicular to the plane of motion. Moreover, the existence of a shear surface wave is caused solely by the magnetostrictive effect is shown.
