a Magnetic susceptibility for a CrSBr single crystal at different relative orientations. b Enlarged low-temperature region showing the susceptibility in zero field cooling (ZFC; filled circles) and field cooling (FC; empty circles) modes. The magnetically ordered temperature regions are highlighted by blue (T < TN) and gray (T < T*) shadings.
