Abstract:
Brillouin scattering spectra of bismuth substituted iron garnets BixY3-xFe5O12 (x = 0, 0.14, 0.36, 0.54) were measured. The thermally excited bulk magnons were observed. Some magnetic parameters of these samples were determined according to the dispersion relation of the bulk magnons. We found that there is a dependance of the spin wave stiffness constant on bismuth contents, the higher the bismuth contents, the smaller the spin wave stiffness constant.
