摘要：

The effects of partial substitution of light rare earths for Sm in (Sm1- xRx)2(Co, Fe, Cu, Zr)17have been investigated where R=Ce, Pr, Nd, Pr.5Nd.5, Ce.2Pr.4Nd.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 Sm.8R.2(Co.633Fe.286Cu.61Zr.020)7.59with R=Ce.2Pr.4Nd.4we obtained Br=11.57 kG,MHc=15.5 kOe, BHc=10.33 kOe, Hk = 10.03 kOe, and (BH)max=30 MGOe. © 1990 IEEE
