| Research Abstract |
Recently, there are many works relating to the vortex core dynamics by spin current. In this research the mechanism of the vortex core rotation and switching by spin current are investigated by using computer simulation. We also investigate the conditions to use this mechanism for magnetic devices. Because these simulation requires huge amount of the computation time, we propose the method to accelerate the calculation speed by using the graphic processing unit.
