A large tunneling magnetoresistance was observed in epitaxial hybrid magnetic tunnel junctions composed of MnAs/AlAs/GaMnAs. The low temperature current-voltage characteristics were in accord with those of a tunneling process through an asymmetric barrier. These experiments confirm that efficient spin injection from metals into semiconductors is possible when a suitable tunnel barrier is used.
