Abstract
Using electromagnetic wave theory in the Voigt configuration, the surface magnetostatic waves (MW) and magnetic polaritons localized at the junction between semi-infinite magnetic superlattice (SL) and magnetic material are analysed theoretically. The general dispersion relation for localized MW and magnetic polaritons are derived by the transfer matrix method in the long-wavelength limit. Some examples of the wave spectra are presented for SL composed of two magnetic materials (Fe/Co). The dispersion curves for different contact materials (contact material with Ni, Co and Gd, respectively) are calculated numerically and the ranges within which surface modes frequencies lie are discussed.
