a The schematic illustration and b the optical image of our experimental setup. Our sample consists of monolayer graphene covering FL-CrI3 stacking on graphite flake (G/FL-CrI3/Gr). c The atomic structure of monolayer CrI3 (top view). d Large-size STM topographic image of G/FL-CrI3/Gr (Vs = 1 V, It = 0.1 nA).
