Electrical injection of spin polarized electrons is observed at ferromagnet-semiconductor interfaces by analyzing the electroluminescence signal of GaAs /(In,Ga)As light emitting diodes (LED) covered with the metals Fe or MnAs. The circular polarization degree of the emitted light reveals a spin pol
