Abstract

We report zero-magnetic-field spin injection from FePt into GaAs at room temperature using FePt/MgO/GaAs-based light-emitting diode heterostructures. Experiments are performed on two samples with different compositions; Fe61Pt39and Fe57Pt43. The polarizations of injected electrons at 0 T for these two samples are at least 1.5% and 3.3%, respectively. The higher zero-magnetic-field injected spin polarization is considered to be due to the better remanent perpendicular magnetization of the FePt layer in the sample with Fe57Pt43. © 2007 Springer Science+Business Media, LLC.
