Abstract

The influence of the pure spin current injection on a domain wall nucleation process in a magnetic wire is investigated by using the nonlocal spin injection technique. The pure spin current injection is found to assist the domain wall nucleation. The spin current responsible for nucleating the domain wall in the nonlocal configuration is comparable to the threshold spin current for the domain wall displacement in the direct current injection. The bias-field dependence of the switching current shows a complicated behaviour. This may be related to the detailed domain structure in the vicinity of the domain wall.
