Moire magnetism in CrBr₃ multilayers emerging from differential strain.

ABSTRACT: Interfaces between twisted 2D materials host a wealth of physical phenomena originating from the long-scale periodicity associated with the resulting moiré structure. Besides twisting, an alternative route to create structures with comparably long-or even longer-periodicities is inducing a differential strain between adjacent layers in a van der Waals (vdW) material. Despite recent theoretical efforts analyzing its benefits, this route has not yet been implemented experimentally. Here we report evidence for the simultaneous presence of ferromagnetic and antiferromagnetic regions in CrBr₃-a hallmark of moiré magnetism-from the observation of an unexpected magnetoconductance in CrBr₃ tunnel barriers with ferromagnetic Fe₃GeTe₂ and graphene electrod
