Reflection and refraction of bulk exchange spin wave on the interface of two ferromagnetic media in planar magnetic field

Abstract

Behavior of spin wave propagation in ferromagnetic medium with non-uniform distribution of magnetic parameters is studied. In particular, the influence of external magnetic field on behavior of bulk spin wave propagating through inhomogeneity made in form of lens (lens is biaxial ferromagnet placed into biaxial ferromagnetic medium with another magnetic parameters. Ferromagnets are in the homogeneous magnetic field directed along the hard axis) is studied.
