What is presented here are the preliminary results of exchange-bias simulation of a single ferromagnetic layer (FM) coupled to an antiferromagnetic (AFM) region with a diluted lattice using a Random Field Ising Model approach. Dilution is simulated by locally enhancement of ferromagnetic coupling constants calculated at random positions with a given dilution level. The results show a direct correlation between exchange-bias and a number of unreversed spins at the FM/AFM interface. Within a dilution level, two components were identified; a global random dilution and a local dilution efficiency. The latter is represented by the coupling constant enhancement. Interpretation of this interfacial effect
