Exchange Bias in CoFe2O4/NiO nanocomposites

Structural and magnetic properties of nanocomposites of ferrimagnetic (CoFe2O4) and antiferromagnetic (NiO) nanoparticles with different percentages of cobalt ferrite (50% and 15% wt) have been studied. The observed Exchange Bias properties and their dependence on interparticle interactions are discussed.
