N2 - Spin electronic structure of the Graphene/Pt interface has been investigated. A large induced spin-orbit splitting (similar to 80 meV) of graphene pi states with formation of non-degenerated Dirac-cone spin states at the (K) over bar -point of the Brillouin zone crossed with spin-polarized Pt 5d states at Fermi level was found. We show that this spin structure can be used as a spin current source in spintronic devices. By theoretical estimations and micromagnetic modeling based on the experimentally observed spin-orbit splitting, we demonstarte that the induced intrinsic magnetic field in such structure might be effectively used for induced remagnetization of the (Ni-Fe)-nanodots arranged atop the interface.
