摘要：

A new III-V nitride-based diluted-magnetic semiconductor GaCrN has been successfully synthesized for the first time. GaCrN layers were grown on sapphire (0001) substrates by electron-cyclotron-resonance plasma-assisted molecular-beam epitaxy. X-ray diffraction measurement showed no existence of secondary phase in the GaCrN layers. They showed a ferromagnetic behavior with a Curie temperature higher than 400 K, and clear saturation and hysteresis were observed in the magnetization versus magnetic field curves at all measuring temperatures.
