Popis:	The effect of interface magnetic dilution on exchange bias is studied with extensive Monte Carlo simulations for a model system consisting of a ferromagnetic layer exchange coupled to a diluted antiferromagnet. The dependence of the exchange bias fields on properties of the ferromagnetic interface layer are identified with particular emphasis on magnetic dilution and bond distribution effects across the interface. It is shown that some dilution of the ferromagnetic interface layer can lead to an increase in the bias field magnitude, even though the net exchange interaction across the interface is reduced.
