Query: Magnetoelastic waves in thin films   This paper discusses the physics of magnetoelasticity and magnetoelastic
waves as well as their mathematical description. Magnetoelastic waves occur as
a result of strong coupling between spin waves and elastic waves in
magnetostrictive ferromagnetic media. In a first part, the basic behavior of
spin waves is reviewed in both bulk ferromagnets as well as in thin films.
Next, elastic waves are discussed with a focus on thin films. Finally, the
interactions between the elastic and magnetic domains are described and it is
shown how this results in the formation of magnetoelastic waves. Based on the
description of bulk magnetoelastic waves, a theory for magnetoelastic waves in
thin films is developed and their dispersion relations are derived. It is shown
that the behavior strongly depends on the geometry of the system, especially on
the polarization of spin and elastic waves and the direction of the
magnetization of the magnetostrictive ferromagnet.
