Correlations in Magnetic Sub‐Domains as an Unconventional Phase Diagram for van der Waals Ferromagnets (Adv. Sci. 26/2025)

van der Waals Ferromagnets The magnetic van der Waals material CrBr3 exhibits an unconventional magnetic order, characterized by the coexistence of multiple domain sub-groups across different layers. To describe these magnetic states, Sergey Y. Grebenchuk, Maciej Koperski, and co-workers developed a phase diagram, revealing that the unique magnetic order arises from weak interlayer exchange coupling and stacking faults, which can also lead to antiferromagnetic coupling between layers.
