Ce-containing (Nd,Ce)-Fe-B-type hybrid magnet was fabricated by die-upset technique using two different types of materials: Ce-substituted (Nd<SUB>0.55</SUB>Ce<SUB>0.45</SUB>)<SUB>15</SUB>Fe<SUB>72.2</SUB>Co<SUB>6.6</SUB>Ga<SUB>0.6</SUB>B<SUB>5.6</SUB> HDDR powder and melt-spun Nd1<SUB>3.6</SUB>Fe<SUB>73.6</SUB>Co<SUB>6.6</SUB>Ga<SUB>0.6</SUB>B<SUB>5.6</SUB> flakes. Magnetic performance of the hybrid magnet was superior to that of the single alloy magnet when they had identical overall composition: <SUB>i</SUB>H<SUB>c</SUB> = 6.8 kOe, Mr = 10.6 kG, and (BH)<SUB>max</SUB> = 19.8 MGOe for the Ce-containing hybrid magnet and iHc = 3.9 kOe, Mr = 9.8 kG, and (BH)<SUB>max</SUB> = 11.6 MGOe for the magnet from the single alloy HDDR powder. Die-upset hybrid magnet consisting of two constituent materials showed smooth and single-material-like demagnetization behavior, and this was attributed to the exchange interaction between neighbouring grains in the magnet.
