The angular dependence of coercivity in Sm(Co,Fe,Cu,Zr)z magnets is investigated with the micromagnetic finite element method. The results show that the mechanism of the magnetization reversal changes from the domain wall pinning to magnetization uniform reversal with the increase of the angle between the easy axes and the applied field. According to the results of calculation, the microstructural parameter αφ is determined.
