Magnetization precession motion in local area in magnetic film propagates to surroundings. It is called as a spin wave, which is expected to application of a new computing using its interference effects. An excitation method of spin waves is Spin-Orbit Torque (SOT). It is occurred when the direct current is applied to non-magnetic metal / magnetic metal. In this presentation, we report results on numerical simulation of excitation current density and distance dependence on local magnetization dynamics excited by SOT.
