摘要：

We both analytically and numerically show the existence of a drift of Bloch walls when submitted to a uniform parallel-to-the-wall-plane rotating magnetic field. The drift velocity changes sign with Bloch wall handedness and is proportional to the amplitude square of the magnetic field, when the latter is small.
