| Research Abstract |
We developed the micromagnetic simulation including non-uniform spin current distribution, and investigated current-induced domain wall motion in a nanowire. As a result, in an in-plane magnetization nanowire, the influences of notch shape and pulse current on the critical current density driving domain wall motion were clarified. Moreover, the multi-bit motion in a nanowire with perpendicular magnetic anisotropy was demonstrated, and a new issue to realize a nanowire memory was suggested.
