Ce-containing (Nd,Ce)-Fe-B-type hybrid magnet was fabricated by die-upset technique using two different types of materials: Ce-substituted (Nd_0.55Ce_0.45)₁₅Fe_72.2Co_6.6Ga_0.6B_5.6 HDDR powder and melt-spun Nd_13.6Fe_73.6Co_6.6Ga_0.6B_5.6 flakes. Magnetic performance of the hybrid magnet was superior to that of the single alloy magnet when they had identical overall composition: iHc = 6.8 kOe, Mr = 10.6 kG, and (BH)_max = 19.8 MGOe for the Ce-containing hybrid magnet and iHc = 3.9 kOe, Mr = 9.8 kG, and (BH)_max = 11.6 MGOe for the magnet from the single alloy HDDR powder. Die-upset hybrid magnet consisting of two constituent materials showed smooth and singlematerial- like demagnetization behavior, and this was attributed to the exchange interaction between neighbouring grains in the magnet.
