We demonstrate room-temperature spin injection from the epitaxially grown ferromagnetic metal Fe₃Si into the semiconductor GaAs. The injection efficiency is comparable to values previously obtained for the Fe/GaAs and MnAs/GaAs hybrid systems using the emission of similar (In,Ga)As/GaAs light-emitting diodes for the detection of spin polarization. The temperature dependence of the detected polarization is explained by taking into account spin relaxation inside the semiconductor device.
