摘要：

A simple modelling of surface roughness in magnetic thin films shows that roughness tends to unpin spin waves at external surfaces. This unpinning effect increases with the roughness height as long as this height remains small. In spin wave resonance, the spin wave intensity spectrum is shown to be quite sensitive to roughness, and new surface spin waves appear because of this roughness.
