The hysteresis loops, angular distribution, nucleation field, coercivity and energy product are calculated by three-dimensional micromagnetic method for Nd2Fe14B/Fe65Co35 bilayers with a deviation of the easy axis, and the results are compared with the experimental results. The results show that obvious nucleation can be observed only when the β between the easy axis and the applied field is equal to 0°, and the nucleation field and the coercivity decrease as the thickness of the soft phase Ls increases. The remanence decreases and the squareness of the hysteresis loop weakens as β increases, leading to the decrease of the energy product while the largest maximum energy product (561.61 kJ/m3) occurs at Ls=1 nm and β=0°. The shapes of the hysteresis loops, the remanence and the coercivity obtained from calculations and experiments are close to each other.
