Spin transport in a Zigzag normal/ferromagnetic graphene junction
Shi Hao-Sheng†, Grigoryan Vahram L.
       
Normal/Ferromagnetic junction constructed with infinite N = 8 AZNGR. N is the number of honeycomb units in a primitive cell. The width and lattice vector with constant a are labeled on the graph. External magnetism is induced with a magnetic insulator attached on top of the semi-infinite graphene ribbon, whose direction is along the z axis.
