Research on the application of the most abundant rare-earth elements for permanent magnetic materials has gained intense interest. However, the magnetic properties decrease dramatically with the increase of Ce content due to the traditional Ce substitute for Nd. A double main phase alloy method has been performed to adjust the composition and combination of main phases in the magnets and make a partial main phase without Ce, which can maintain higher remanence. The influence of Ce content on the rectangularity of demagnetization curves and magnetic properties of (Nd1-xCex)30 (Fe,TM)balB1 sintered by the double main phase alloy method has been investigated. When the Ce content was 30% of the total amounts of all the rare earth metals, the maximum energy product of the sintered magnet, was still over 43 MGOe.
