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.
