This paper provides the results of exchange-bias simulation of a single ferromagnetic (FM) layer coupled to a quenched antiferromagnetic (AFM) region using a Random Field Ising Model (RFIM) approach. Using the RFIM algorithm the shapes of exchange-biased hysteresis loops, featuring perpendicular magnetic anisotropies, were obtained. Providing a possible explanation of this effect the recognized stable part of an interface magnetisation represented by unreversed spins at the interface was evidently simulated. Obtained results are consistent with the Domain State Model (DSM) model, where a part of the AFM interface magnetisation is stable during hysteresis loop creation
