Triggering and probing of phase-coherent spin packets by time-resolved spin transport across an Fe/GaAs Schottky barrier
L. R. Schreiber, C. Schwark, S. Richter +7
Time-resolved electrical spin transport is used to generate and probe spin currents in GaAs electrically. We use high bandwidth current pulses to inject phase-coherent spin packets…
Optical and electrical spin injection and spin transport in hybrid Fe/GaAs devices
S. A. Crooker, M. Furis, X. Lou +4
We discuss methods for imaging the nonequilibrium spin polarization of electrons in Fe/GaAs spin transport devices. Both optically- and electrically-injected spin distributions are…
Spin injection from perpendicular magnetized ferromagnetic -MnGa into (Al,Ga)As heterostructures
C. Adelmann, X. Lou, H. -S. Chiang +5
Electrical spin injection from ferromagnetic -MnGa into an (Al,Ga)As p-i-n light emitting diode (LED) is demonstrated. The -MnGa layers show strong perpendicular magnetocryst…
Electrical Detection of Spin Accumulation at a Ferromagnet-Semiconductor Interface
X. Lou, C. Adelmann, M. Furis +3
We show that the accumulation of spin-polarized electrons at a forward-biased Schottky tunnel barrier between Fe and n-GaAs can be detected electrically. The spin accumulation lead…
Electron Spin Dynamics and Hyperfine Interactions in Fe/Al_0.1Ga_0.9As/GaAs Spin Injection Heterostructures
J. Strand, X. Lou, C. Adelmann +4
We have studied hyperfine interactions between spin-polarized electrons and lattice nuclei in Al_0.1Ga_0.9As/GaAs quantum well (QW) heterostructures. The spin-polarized electrons a…
Spin injection from the Heusler alloy Co_2MnGe into Al_0.1Ga_0.9As/GaAs heterostructures
X. Y. Dong, C. Adelmann, J. Q. Xie +6
Electrical spin injection from the Heusler alloy Co_2MnGe into a p-i-n Al_0.1Ga_0.9As/GaAs light emitting diode is demonstrated. A maximum steady-state spin polarization of approxi…
