Abstract :
In this study, it was shown that a uniform ferromagnetism collapses into a multi-domain configuration when spin current density is above the critical spin current density in which domain walls are flowing due to spin current. This is supported by explicit energy comparisons of the uniformly magnetized and domain wall state under spin current.
