Graphene spin filtering via magnetic proximity

Caption

Schematic of a graphene superlattice in contact with a cobalt magnetic electrode. In the region next to the cobalt electrode, magnetic proximity induces spin splitting in the graphene bands, enabling tuneable Fermi level–dependent spin filtering. Spin up states (red) become enhanced relative to spin down states (blue) leading to large spin polarisation. Outside the electrode’s influence, both spin species return to their equilibrium, shown in the non-illuminated region.
