Magnetic proximity effect in graphene on 2D van der Waals magnets

Over the past few years, a growing family of van der Waals (vdW) materials have been discovered to host intrinsic magnetic ordering. These materials exhibit a wide array of magnetic orders in the atomically-thin limit, including both intra- and inter-layer ferro- and antiferromagnetism. Interfacing graphene with these 2D magnets offers intriguing possibilities for realizing new phenomena stemming from the magnetic proximity effect (MPE) owing to the high quality of the layered junction. Here, we investigate the MPE in heterostructures comprising graphene on XPS₃ (X=Ni/Fe/Mn) substrates. Our magnetotransport characterization reveals signatures of charge transfer effects in a variety of these heterostructures. We will additionally discuss ongoing efforts to fabricate pristine interfaces between graphene and the environmentally-sensitive 2D magnets.
