We have investigated the bias field(He) and the coercivity(Hc) of the exchange bias effect in the Ni80Fe20/Fe50Mn50 bilayers and the simulated experimental data based on Mauri model. It is found that the simulation is to some extent consistent with the experiment on the whole variation trend of the coercivity, whereas the calculated result is smaller than the experimental data. On the other hand, the simulation indicates that the coercivity drops down sharply with the deflection of the applied magnetic field from the unidirectional axis to its perpendicular orientation, while it decreases slower in the experiments.
