Spin pumping into two-dimensional electron systems
arXiv:1609.09556 · doi:10.1103/PhysRevB.94.205428
Abstract
We study the spin current injected by spin pumping into single layer graphene and the two-dimensional electron gas (2DEG) with ferromagnetic contacts using scattering theory. The spin currents pumped into graphene are very distinct from that into the 2DEG since importantly affected by Klein tunneling.
