Schematic spin electronic structure of the Dirac-cone graphene π states for the Graphene/Pt interface with a large spin-orbit splitting of the π states at the Fermi level near the K and K' points (a), and the difference between the contributions to the excited current of electrons with opposite spin orientations realized when setting up an electrical gradient (∇U) between the ends of the system (b). (c) Schematic presentation of the proposed device construction with the (Ni-Fe)-nanodots deposited atop the Graphene/Pt interface. The construction with thin Pt-stripes can be arranged on top of SiC.
