We have successfully investigated the structural and electronic properties of SLG/YIG(111) using ARPES measurements. The ARPES intensity map at a constant binding energy of 0.2 eV below the Fermi level reveals two sets of Dirac points exhibiting the characteristic sixfold symmetry, suggesting that the major domains are rotated by 30 degrees relative to each other. The ARPES intensity map along the gamma-K direction indicates p-type doping in SLG/YIG(111). The presence of spin-polarized Dirac electrons in SLG/YIG(111) is also demonstrated. These results highlight the potential of graphene/YIG heterostructures for applications in graphene-based spintronic devices, including spin field-effect transistors
