magneto-transport in graphene- based ferromagnetic/Rashba barrier/ferromagnetic hetero-junction

The tunnelling of spin-polarized electrons through a Rashba barrier on a single layer graphene is studied bythe scattering matrix method. It is shown that graphene sheets in the presence of Rashba spin- orbit barrier will act as an electron spin-inverter and conductance for the spin up incident electrons (G) oscillates with the Rashba intensity.
