Prof Thorsten Hesjedal: Magnetic Skyrmions

Magnetic skyrmions are magnetisation swirls with unique topological properties, leading to a number of novel physical effects such as emergent electromagnetism and non-trivial magnetic dynamics. The prototypical skyrmion-hosting materials are chiral magnets, in which the long-range ordered skyrmion lattice is found as the bulk state. Depending on the material, the individual skyrmion size in chiral magnets falls in the range of 3-100 nm. Owing to their small size and topological stability, skyrmions are considered as next-generation binary information carriers. Here, I will present an overview of the field of skyrmionics, covering the concept of topology, skyrmion materials, magnetic characterisation techniques, a critical review of device applications, and an outlook on future developments.
