摘要	Exchange bias (EB) and magnetic properties of ferrimagnetic (FI) Fe(3)O(4) and antiferromagnetic (AFM) Cr(2)O(3) nanocomposites prepared by mechanical alloying have been investigated. A large EB field of 2.2 kOe at 10 K is observed in one of the nanocomposites, which may be related to the uncompensated and pinned AFM spins at the interface between FI and AFM phases of the nanocomposites. The EB field varies with the strength of cooling field and the content of the Cr(2)O(3) phase, the phenomena observed are explained in terms of interfacial exchange interaction between the two phases.
