Spin-dependent photoelectron tunneling from GaAs into magnetic cobalt

D. Vu, H. Jurca, F. Maroun, P. Allongue, N. Tournerie, A. Rowe, D. Paget, S. Arscott, Emilien Peytavit

The spin dependence of the photoelectron tunnel current from free standing GaAs films into outof-plane magnetized Cobalt films is demonstrated. The measured spin asymmetry (A) resulting from a change in light helicity, reaches ±6% around zero applied tunnel bias and drops to ±2% at a bias of -1.6 V...
