Computer modeling of two-layer system from antiferromagnetic and ferromagnetic films is carried out. The Ising model is used. Wolf ′s cluster algorithm is used for calculations. Phase transition temperatures are determined. A state with an ordered antiferromagnetic film and a disordered ferromagnetic film is selected for examination. Dependence the ferromagnetic film magnetization on parameters of antiferromagnetic film is determined. Computer simulation of ferromagnetic film behavior in external magnetic field is performed. The value of the anti-ferromagnetic bias field is determined from the comparison these two experiments. The dependence of the bias field on the exchange integral value at the film boundary is determined.
