Micromagnetic Simulation of Vortex Core Reversal

Caption

Figure 2: Micromagnetic simulation of the reversal of the vortex core with a short magnetic pulse. (a) Initial status: vortex core points downwards; (b) additional upwards magnetization becomes visible; (c) a double peak forms: a vortex-antivortex pair; (d) final status: after the original vortex has been eliminated by the antivortex, a vortex core pointing upwards remains.
