中文摘要	The influence of microstructure on magnetic properties of Sur ( Co, Cu, Fe, Zr). magnets is investigated by rmicromagnetic finite-element method. The demagnetization curves at different temperatures are also simulated. The calculated results show that the saturation polarization J(s) depends on the relative proportions of 2:17 phase and 1 :5 phase. The coercivity and the maximum energy product increase with increasing 2:17-type cell size, while they decrease with increasing width of I :5-type cell boundary. The coercivity analysis shows that the magnetization reversal in Sm( Co, Cu, Fe, Zr). magnets is mainly controlled by nucleation at cell boundary. The abnormal temperature dependence of coercivity is due to the fact that the cell boundary becomes less magnetic even nonmagnetic and the nucleation is difficult with increasing temperature.
