Recent progress in exploring the magnetic solids with room-temperature skyrmionic spin configurations

Magnetic materials with skyrmionic spin configurations have been widely investigated in recent years owing to their promising applications for magnetic memory storage and logic circuits. Considering their practical applications, room-temperature skyrmion-hosting magnetic materials shall be investigated comprehensively. The characteristics of magnetic skyrmions are closely associated with the physical properties of the host magnetic materials. The symmetry of the crystal structure, magnetic order temperature, and geometric shape of magnetic materials significantly affect the formation and annihilation of magnetic skyrmions. In addition to the intrinsic properties of materials, detection methods are vital to the investigation of new materials. Herein, the techniques for detecting magnetic skyrmions are briefly summarized, and the results of room-temperature magnetic skyrmion hosting magnetic solids (the artificial materials are not included) with different topological characteristics from recent years are presented.
