Perfect valley and spin polarizations in a superlattice of ferromagnetic gapped graphene with spin-orbit coupling
Journal of Magnetism and Magnetic Materials（2019）
Abstract
•Full spin and valley polarized currents can be achieved simultaneously.•Spin and valley polarizations oscillate with the gate voltage.•The direction of currents can be electrically controlled by the gate voltage.
