The phenomenon of exchange bias was discovered in 1956 by Meiklejohn and Bean [10], For systems exhibiting a FM/AF interface, the cooling in an external field typically results in a shifted or biased hysteresis loop. Upon field cooling from above the Neel temperature of the AF, interface ordering sets in at the so called blocking temperature (TB), and the...

A systematic shift in the loop to the left is apparent on field cooling and originates from the phenomenon of exchange bias [32-35] associated with the exchange anisotropy created at the interface between antiferromagnetic (AFM) and ferromagnetic (FM) phases as first observed in nanosized oxidized Co nanoparticles [32],...
