Altermagnetic states hold promise for spintronic applications but are yet to be observed in twisted van der Waals materials. Now an orthogonally twisted CrPS₄ homostructure is shown to exhibit signatures of altermagnetism. ↧ Altermagnetism in twisted van der Waals homostructures Nature Physics - Altermagnetic states hold promise for spintronic applications but are yet to be observed in twisted van der Waals materials.
