Abstract

We have studied the current-induced dynamics of the transverse domain wall in the adiabatic limit. Above the threshold current density for the continuous domain wall motion, the transverse wall is transformed by the injection of the antivortex. In general, the wall velocity increases and the wall width decreases as the antivortex is injected. However, detailed time-dependent profiles of the wall velocity and the wall width are significantly affected by the aspect ratio of the nanostrip. The mean velocity of the TW decreases as the aspect ratio increases.
