ABSTRACT
We demonstrate direct experimental evidence of domain wall motion driven by a magnetic field in a magnetic microwire. The velocity of the elliptically shaped domain wall significantly increases with increasing domain wall inclination with respect to the axis of the wire. The Walker breakdown has been found in the presence of circular magnetic field. We develop an analytical model describing the motion of inclined elliptically shaped domain walls in a steady regime. The controllable mobility of the domain wall using ultra-low magnetic field is determined by the increase of domain wall length.
