The temperature dependence of magnetization of intermetallic compounds molecular field theory (MFT)were studied and the results were consistent with the experimental data, so the Curie temperatures were obtained.The exchange field HMn (T) and HGd (T) were presented.The saturation magnetization and the Curie temperature Tc decrease with the increasing Er content.But the rare earth exchange field strengthens, which leads to increasing magnetocrystalline anisotropy.The exchange coupling constants JFeFe, JFer, Jrr were caculated.JFeFe dominates the three kinds of interaction, implying that the magnetic interaction is dominated by the exchange 3d electrons.
