The possibility of excitation of magnetoacoustic surface waves by an rf field on Bloch domain walls is considered. The investigation indicates that dispersive and nondispersive surface waves may be generated. The resonance frequency of magnetic moment vibrations in a Bloch wall near specimen surface is received. When the rf field lies in the easy axis of magnetization the magnetoacoustic surface waves are excited actually in one side. The consideration is restricted to the case of dilute YIG for simplicity.
