We develop a simple analytic theory for the existence and electrical control of perpendicular magnetic anisotropy (PMA) based on the Rashba spin-orbit interaction and the single band Stoner model of magnetism. We show the competition between the Rashba spin-orbit fields and the exchange interaction, reflecting electron correlations. This theory can potentially lead to a very large magnetic anisotropy arising from the internal electric fields, , which exist at, e.g., ferromagnetic/metal and ferromagnetic/oxide insulator interfaces but modified by the addition of an applied electric field . There is a Rashba splitting of the band structure leading to a quadratic, , contribution to the magnetic anisotropy, contrasting with a linear in doping effect.

We show that the Rashba effect at a ferromagnet/nonmagnet interface induces the interfacial magnetic anisotropy. While the Rashba effect itself stabilizes the in-plane magnetic configuration parallel to the interface the competition between the Rashba effect and the ferromagnetic exchange interaction leads to the perpendicular magnetic anisotropy. In this talk, we focus on the possible Rashba effect at the interface between a single layer graphene and a ferromagnetic thin layer and the induced perpendicular magnetic anisotropy.
