Abstract: We present a simultaneous investigation of coherent spin dynamics in both localized and itinerant carriers in Fe/GaAs heterostructures using ultrafast and spin-resolved pump-probe spectroscopy. We find that for excitation densities that push the transient Fermi… read more here.

Abstract: Abstract Low-temperature circularly polarized electroluminescence in InGaAs/GaAs/δ-〈Mn〉 heterostructures has been studied. It is established that the degree of circular polarization weakly depends on spatial separation of the active region and magnetic layer and is retained… read more here.
