Graphene is a promising candidate for applications in spintronics. In this paper, Density Func- tional Theory method is used to calculate the band structure and magnetic properties of graphene on Ni(111). Our results show that once there is anti-ferromagnetic order in graphene, an external electric field at the order of 109 V/m can induce a gap width difference of tens of meV for opposite spin states near the Fermi surface.
