A novel heterostructure consisting of single-layer graphene (SLG) and half-metallic Co2Fe(Ge0.5Ga0.5) (CFGG) Heusler alloy ferromagnet were synthesized, and the electronic properties of the interface were examined by depth-resolved X-ray magnetic circular dichroism spectroscopy. We found that in the SLG/CFGG heterostructure the SLG has a quasi-free-standing nature and the CFGG preserves the half-metallic ferromagnetism in the vicinity of the interface, which suggested that the SLG/CFGG heterostructure possesses distinctive advantages over other reported graphene/ferromagnet heterostructures for realizing high-performance spintronics devices.
