Cu2OSeO3 Turns Trigonal with Structural Transformation and Implications for Skyrmions
Alla Arakcheeva, Priya Ranjan Baral, Wen Hua Bi +3
The formation and characteristics of magnetic skyrmions are strongly governed by the symmetry of the underlying crystal structure. In this study, we report the discovery of a new t…
