Initial/final state selection of the spin polarization in electron tunneling across an epitaxial Fe/GaAs(001) interface
Spin dependent electron transport across epitaxial FeGaAs (001) interfaces has been investigated using photoexcitation techniques. Spin filtering is observed in the forward bias regime and its sign is switched by using different photon energies. First principles calculations suggest that the spin po...
