      Highly efficient spin filtering of ballistic electrons 

      Steinmuller, S. J.; Trypiniotis, Theodossis; Cho, W. S.; Hirohata, A.; Lew, W. S.; Vaz, C. A. F.; Bland, J. A. C. (2004)
      Spin dependent electron transport in hybrid Au/Co/Cu/NiFe/n-GaAs spin valve Schottky barrier structures was investigated using photoexcitation at various wavelengths. For excitation with the photon energy well above the ...

      Highly efficient spin filtering of ballistic electrons in hybrid spin valve/semiconductor structures 

      Steinmuller, S. J.; Trypiniotis, Theodossis; Hirohata, A.; Cho, W. S.; Lew, W. S.; Vaz, C. A. F.; Bland, J. A. C. (2004)
      The highly efficient spin filtering of ballistic electrons in hybrid spin valve/semiconductor (SC) structures was discussed. It was found that the photocurrent was dependent on the relative alignment of the light helicity ...
