Dynamics of magnetic skyrmions

We review the recent progress on the magnetic skyrmions in chiral magnetic materials.The magnetic skyrmion is a topological spin configuration with localized spatial extent,which could be thought of as an emergent rigid particle,owing to its particular topological and chiral properties.Static skyrmionic configurations have been found in various materials with different transport and thermodynamic properties.The magnetic skyrmions respond to externally applied fields in a very unique way,and their coupling to other quasiparticles in solid-state systems gives rise to the emergent electrodynamics.Being not only theoretically important,the magnetic skyrmion is also very promising to be the information carrier in next generation spintronic devices.
