A magnetic skyrmion, a particle-like spin swirling object, has a nontrivial topology and is seen as a promising next-generation information carrier in high-performance spintronic devices. This study delves into the magnetic properties of skyrmion-hosting materials stemming from DMI, highlighting the relationship between materials' point groups and DMI, as well as the common features of magnetic skyrmions experimentally verified in magnetization and magnetotransport measurements. Discussions also include other particle-like magnetic configurations in chiral magnets and their crossover with superconductors.
A magnetic skyrmion is a particle-like spin swirling object with a nontrivial topology that holds great promise for next-generation information carriers in high-performance spintronic devices. It was discovered in a chiral magnet, MnSi with B20 structure, in 2009 and later confirmed as a common feature of magnetic compounds with Dzyaloshinsky-Moriya interaction (DMI). In this work, we provide fundamental insight into the magnetic properties of skyrmion-hosting materials originating from DMI. The relationship between the point groups of the materials and DMI is introduced; then, the common features of magnetic skyrmions experimentally verified in the magnetization and magnetotransport measurements are highlighted. Finally, other particle-like magnetic configurations in chiral magnets and the crossover with a superconductor are discussed.
