(a) Schematics of BLS experiment and possible atomic arrangement at the interface. (b) BLS spectra for DE spin waves recorded at a fixed incident angle with $k=16.7\mathrm{rad}/\mu m$ under oppositely oriented external magnetic fields $H$. The solid lines represent fittings with Lorentzian functions.
