Interfacial and low-dimensional magnetic skyrmions

Magnetic skyrmions, nanomagnetic structures with high topological proper‐ ties, high speed, small size, and low motion-driving current density, have received wide attention. They may be expected to function as ideal information carriers for ultra-high density magnetic storage and logic function devices in the future. These magnetic skyrmion-based devices have the advantages of non-volatile high-density storage, high read/write speed, and low-energy consumption. Moreover, the combination of topology and magnetism renders them a good platform for the study of topological magnetism. Here, we briefly describe the history and topological physics of magnetic skyrmions, then discuss their use in magnetic thin films and two-dimensional magnetic materials. We hope that this review can pave an avenue for further studies of skyrmion-based spintronics.
