Abstract

Theoretical and experimental studies are made of the spectra of spin wave excitations localized at a Bloch domain wall in a ferromagnet with combined cubic and biaxial anisotropy in [100]- or [110]-oriented bismuth-containing iron garnet films. This analysis of the spectra is used as the basis to calculate diagrams of stable states of a homogeneous Bloch domain wall as a function of the magnetic parameters in these materials. Results of measurements of the oscillation spectrum of an isolated domain wall in the mega- and gigahertz frequency ranges are presented. A description is given of an effect where the spin-wave excitations of the Goldstone translational branch and the high-frequency Gilinskii unidirectional mode are hybridized.
