Experimental Findings

We have used the Monte Carlo simulation technique to investigate the mechanism that gives the exchange bias effects on composite magnetic nanoparticles with Ferromagnetic (FM) core/Antiferromagnetic (AFM) shell morphology. Our study shows that:. (a) the exchange bias field depends mainly on the structure of the interface and less on its size,. (b) when the shell size becomes bigger than the core size the exchange bias field decreases,. (c) the size of the vertical shift depends on the total number of uncompensated spins in the nanoparticle and. (d) the training effect has its origin to the rearrangement of the spins at the FM/AFM interface. Our results are in good agreement with experimental findings.
