Dynamics of magnetic skyrmions
Dynamics of magnetic skyrmions |
| Fig.#cod#x00A0;10. The depinning process of a skyrmion via an electric current pulse. a During the application of the current t =0#cod#x2013;200, the system energy exceeds the pinning energy; after that the system energy decreases with time because of the Gilbert damping. b The depinning#cod#x2013;pinning trajectory. There are two pinning centers in the simulation, one at 0,0 and the other at 40,0. The skyrmion is depinned from 0,0 and then pinned again at 40,0. The black dot shows the position of the skyrmion when the current stops at t =200. [ 12 ] |
