Abstract/Summary:
Magnetic Skyrmion is a topological stable, particle-like spin texture. Its unique proper- ties such as curren-driven motion and topological protected make it to be a candidate for future spintronic devices. However, Skyrmion dynamics are still not that clear to build real devices. To investigate those Skyrmion dynamics, a code was developed to solving the Landau-Lifshitz-Gilbert Equation. Skyrmion dynamics with spin waves is investigated by micromagnetic simulations, we find that the scattering angle of the spin wave is related to the size of Skyrmion. We also show the simulation of the topological hall effect that maybe used to read a Skyrmion. Based on the current dynamic properties of Skyrmion, we proposed a Skyrmion-based architecture.
