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…
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 and Relaxation in Ferromagnet-Semiconductor Heterostructures
C. Adelmann, X. Lou, J. Strand +2
We present a complete description of spin injection and detection in Fe/Al_xGa_{1-x}As/GaAs heterostructures for temperatures from 2 to 295 K. Measurements of the steady-state spin…
Nuclear Magnetic Resonance in a Ferromagnet-Semiconductor Heterostructure
J. Strand, B. D. Schultz, A. F. Isakovic +3
We report the observation of nuclear magnetic resonance (NMR) in a ferromagnet-semiconductor heterostructure in the presence of a spin-polarized current. Spin-polarized electrons i…
