Abstract

The electronic and magnetic properties of the interface formed between graphene and the multiferroic van der Waals material CuCrP2S6 are studied using X-ray spectromicroscopy, accompanied by DFT calculations. These results demonstrate the free-standing character of slightly p-doped graphene, protecting the underlying materials from the environment, while preserving the Dirac cone for the graphene-derived bands. Despite the strong ferromagnetic ordering of Cr3+ moments, there is no evidence of proximity effect at the graphene/CuCrP2S6 interface. Our findings and detailed studies of graphene interfaced with different multiferroic materials will aid in its further implementation in various applications.
