Abstract Brillouin light scattering measurements were performed in the backscattering geometry on a Bi-substituted rare earth iron garnet. We observed two different peaks: One is attributed to a surface spin w...ave in the dipole-exchange regime while the other is referred to as a backscattering magnon mode, because the incident light in this case was scattered backward by exchange-dominated spin wave inside the material. We propose a method to estimate the exchange stiffness constant from the frequency of the backscattering magnon mode. The obtained value is comparable with the previously reported values for Y_3Fe_5O_12.show more
