Layered van der Waals magnets like CrSBr, when sandwiched between electrodes form a natural magnetic tunnel junction, albeit lacking the characteristic nonmultiple volatile states at zero field of a magnetic memory. Here, Chen et al overcome this limitation to establish four nonvolatile states at zero field by constructing magnetic tunnel junctions out of twisted monolayers and bilayers of CrSBr with two twisted interfaces.
