[20a-131-7] Dynamics of a Skyrmionium by Spin-Transfer-Torque
Keywords:spintronics, skyrmionium
Magnetic skyrmioniums are chiral and vortex-like spin structures. The direction of magnetization of a magnetic skyrmionium rotates once when we go away from its center. A topological number of a magnetic skyrmionium is Q = 1 + (- 1) = 0, which means that it is composed of a skyrmion and an anti-skyrmion. In this presentation, we report dynamics of a magnetic skyrmionium by spin-transfer-torque using micromagnetic simulations.
