Abstract:	We have studied the exchange bias at the ferromagnetic (FM)/ antiferromagnetic interface in the zinc-blende transition-metal chalcogenides, CrTe (5 nm)/MnTe(40 nm) bilayer grown on GaAs (100) substrate by molecular-beam epitaxy. A negative exchange bias shift in the hysteresis loop is observed when the bilayer is cooled in the applied magnetic field. The temperature-dependent remanent magnetization shows a clear enhancement of the Curie temperature and magnetization in the bilayer as compared to a single FM layer. The effects of temperature, cooling field, and angular dependence on the exchange bias have been investigated. © 2009 American Institute of Physics.
