The influence of inhomogeneous exchange on the propagation of surface damon–eschbach waves in the ferrospinels films

Abstract

The law of magnetostatic waves dispersion in the manganese and magnesiummanganese ferrospinels films was investigated using the moving-transducer method. The wave numbers, phase and group velocities of magnetostatic waves are defined. The excitation of spin-wave waves in the surface layer of the film is found. The wave numbers, spin pinning options, their frequency dependences and surface anisotropy constants are calculated.
