Notes:
Nd2Co17 alloy exhibits a saturation magnetization about 30% higher than that of Sm2Co17 at room temperature. However, the former is not a useful material for permanent magnet fabrication due to its basal plane anisotropy near room temperature. In this study, an attempt is made to investigate the effect of partial substitution of Nd2Co17 with other elements. In particular, alloys of the compositions Nd2−xSmxCo13Fe4 and Nd2Co13Fe4−xTx (where T=Zr or Mn) have been examined. The results obtained in this investigation show several interesting trends in the behavior of these alloys. Substitution of ∼20% Sm in Nd2−xSmxCo13Fe4 decreases the spin-reorientation temperatures from 613 to 224 K. Further, an increase in x up to 1.0 causes only a moderate decrease in the saturation magnetization but results in a considerable enhancement of the anisotropy field. Typical thermomagnetic curves of Nd2Co13Fe4−xTx (T=Zr,Mn) exhibit spin-reorientation temperatures. These results are discussed in terms of preferential substitution of Zr or Mn in this system.
