  • Abstract
    The effects of partial substitution of light rare earths for Sm in (Sm1-xRx)2 (Co,Fe,Cu,Zr)17 have been investigated where R=Ce, Pr, Nd, Pr0.5Nd 0.5, Ce0.2Pr0.4Nd0.4 and x=0-0.5. Experiments show that both remanence and maximum energy product are improved for x=0.1-0.2, depending upon compositions and heat treatments. For a composition Sm0.8R0.2(Co0.633Fe0.286 Cu0.061Zr0.020)7.59 with R =Ce0.2Pr0.4Nd0.4, the authors obtained Br=11.57 kG, MHc =15.5 kOe, BHc=10.33 kOe, Hk=10.03 kOe, and (BH)max=30 MGOe
