摘要: Using the Green-function formalism, we calculate a current-induced spin polarization of weakly magnetized graphene with Rashba spin-orbit interaction. In general case, all components are nonzero, contrary to nonmagnetic limit, where only nonvanishing component is that in plane and normal electric field. When induced exchange coupled magnetization, it exerts torque on latter. method, have derived some analytical formulas for also determined corresponding components. The results compared those obtained numerically. Vertex corrections due scattering randomly distributed impurities calculated shown enhance bare bubble approximation.
