Abstract

We performed micromagnetic study on current induced domain wall motion for the vortex type wall. It has been proposed two spin torque terms, i.e. adiabatic and nonadiabatic terms. Especially, the nonadiatic torque was introduced to explain a continuous motion of domain wall by spin torque. Here, we show a vortex wall continuously move without taking into account the nonadiabatic torque term. Detailed transformation of spin structure is discussed.
