Abstract: Ce-based magnets development can reduce the excessive consumption of Pr and Nd elements. The low Curie temperature of Ce-Fe-B alloy and CeFe₂ phase disadvantage on the magnetic properties limit the application of Ce-based magnets. In this manuscript, Ce_13-xGd_xFe₈₁B₆(x = 0.3, 0.7, 1, 4)alloy ribbons were prepared by melt quenching method by the substitution of Gd for Ce. The phase composition and magnetic properties were also studied. The results show that the Ce_13-xGd_xFe₈₁B₆ alloy ribbon consists of 2:14:1 main phase, a small amount of CeFe₂ phase and α-Fe. The Gd substitution can improve the comprehensive performance. The alloy ribbons coercivity increases with the increase of Gd substitution when substitution of Gd is less than 4 at. %. The Curie temperature and the thermal stability of the alloy ribbon also increase with the increase of Gd substitution.
