【 摘 要 】

Influence of crystallographic magnetic anisotropy on dispersion laws of magnetostatic spin waves is discussed. Classification of waves spectra in single crystal films of ferrites is given. The scale of magnetic anisotropy influence on spectra of volume and surface types of waves is investigated. The film model with cubic magnetic anisotropy is constructed and expressions for components of a tensor of the effective demagnetization anisotropy factors are deduced. Results of spectra calculation of magnetostatic waves in a film of yttrium iron garnet are given.
