The (Co2MnSi)1-x-(NiO)x(x = 0.0, 0.1, 0.2, 0.3) nanocomposites were fabricated by mechanical alloying using Co2MnSi Heusler alloy and NiO nanoparticles. It is revealed that antiferromagnetic NiO nanocrystallines dramatically enhances the magnetoresistance of the nanocomposites more than 20 times larger than that of the NiO-free Co2MnSi alloys at 300 K. The Exchange bias effect of the nanocomposites suggests that the spin-dependent tunneling and scattering at the interfaces of ferromagnetic/antiferromagnetic are responsible for the enhancement of the magnetoresistance.
