  Spin waves can induce domain wall motion in ferromagnets. We derive the
equations of motion for a transverse domain wall driven by spin waves. Our
calculations show that the magnonic spin-transfer torque does not cause
rotation-induced Walker breakdown. The amplitude of spin waves that are excited
by a localized microwave field depends on the spatial profile of the field and
the excitation frequency. By taking this frequency dependence into account, we
show that a simple one-dimensional model may reproduce much of the puzzling
frequency dependence observed in early numerical studies.
