We theoretically investigate spin-resolved currents flowing in large-areagraphene, with and without defects, doped with single atoms of noble metals(Cu, Ag and Au) and 3d-transition metals (Mn,Fe,Co and Ni). We show that thepresence of a local magnetic moment is a necessary but not sufficient conditionto have a non zero current polarization. An essential requirement is thepresence of spin-split localized levels near the Fermi energy that stronglyhybridize with the graphene pi-bands. We also show that a gate potential can beused to tune the energy of these localized levels, leading to an external wayto control the degree of spin-polarized current without the application of amagnetic field.
