説明:

Graphene fabricated on magnetic insulators holds great potential for developing novel functional materials and applications in spintronics devices. In the present study, we have investigated the structural and electronic properties of transferred single-layer graphene (SLG) on the yttrium iron garnet (111) [YIG(111)] substrate. Here, spin polarization in SLG/YIG(111) is reported in the previous study. Our angle-resolved photoemission spectroscopy visualizes the electronic band structure of SLG/YIG(111) and demonstrates an intact Dirac band with p-type doping in SLG/YIG(111). Therefore, based on a collaborative consideration of the previous and present studies, we conclude that the spin-polarized Dirac electrons exist in SLG/YIG(111).
