We have achieved perpendicularly polarized spin injection/detection FePt / MgO into GaAs / AlGaAs two dimensional electron gas. We measured the two terminal Hanle voltages with in-plane and out-of-plane magnetic fields at 1.4 K in the Cryostat. By systematically measuring the Hanle signals, we obtained injection current dependence of spin signals.
