Interaction of surface magnetic waves in anisotropic magnetic slabs

Abstract
Group delay of magnetostatic surface wave propagation in parallel layers of magnetic slabs have been considered. The dispersive characteristics depend strongly on the separation between the slabs and their crystal plane orientations with respect to the applied field ?0 where propagation is normal to ?0 and in the plane of the slab. As an example we consider ?0 along 〈100〉 direction in slab (Slab A) in contact with a metal surface and 〈110〉 direction in the other slab (Slab B) exposed to air. Both slabs are (100) planes. The variation of delay time and bandwidth with relative orientation of the two slabs and their thicknesses are shown. Much larger bandwidth is obtained with two magnetic slabs as compared to that of a single magnetic slab configuration.
