Van der Waals materials often exhibit different metastable structures, with the constituent layers shifted by small, atomic scale distances. If the material is magnetic, the resulting different layer stackings can cause drastic changes in magnetic ordering. Here, Yao et al. observe all three locally stable magnetic orderings predicted to occur in CrBr3 multilayers, two antiferromagnetic and one ferromagnetic.
