Abstract
The observation of a number of spin-wave spectra in liquid-phase-epitaxy yttrium-iron-garnet films which cannot be described by a surface anisotropy of the uniaxial type is reported. The strong in-plane angular variation of the spin-wave-mode intensities is explained in terms of a nonuniform anisotropic field localized in the diffusion zone rather than by an artificial surface field.Keywords
