Dispersion of magnetostatic waves in the tangentially magnetized ferrite plate with the anisotropy axis perpendicular to its plane

The law of dispersion of magnetostatic waves (MSWs) in the tangentially mag netized ferrite plate (FP) with the uniaxial anisotropy, whose axis is perp endicular to its plane, is obtained and analyzed in the case when the appli ed constant magnetic field is less than the uniaxial anisotropy field. It i s shown that this model qualitatively describes the MSW dispersion in hexa- and ortho-ferrites and also in a nonsaturated FP.
