a Schematic diagram of backscattering geometry of the BLS measurement. The magnetic field was applied along the y axis. Data were taken in backscattering geometry with different angles θ with respect to the z axis. b BLS spectra of magnetostatic surface spin waves (MSSW) when μ0H = 338.4 mT at θ = 20°. Gray dots are the experimental data collected by BLS. Red lines are fitted curves with Lorentz function. Blue dash lines are the mirror curves of the red lines. Δf is the frequency difference between Stokes and anti-Stokes peaks. c Frequency differences Δf obtained at different field values. Solid lines are linear fits.
