摘要

The law of magnetostatic waves dispersion in the manganese and magnesium-manganese 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.
