Figure 1: Model of heterostructure and electronic properties of ferromagnetic graphene (FMG).

(a) Schematics of the vertical heterostructures with FMG and a tunneling insulator. (b) Spin-resolved band structures and (c) spin density of states (SDOS) of FMG. Red and Green solid lines represent spin-up and down states in FMG with spin-resolved bandgaps and Fermi velocities.
