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 fea-tures of magnetic skyrmions experimentally verified in the magnetization and magnetotransport measurements are highlighted.Finally,other particle-like magnetic configu-rations in chiral magnets and the crossover with a super-conductor are discussed.
