| Abstract: | The Er2Fe17Cx compounds with high carbon contents have been prepared by melt-spinning. The structures, phase stability and intrinsic magnetic properties of Er2Fe17Cx(x=0. 0, 0. 5,1. 0,1. 5,2. 0,2. 5,2. 8 and 3.0 ) have been investigated in detail. The influence of interstitial carbon atoms on atomic moments, exchange interaction and anisotropy has been discussed. At the same time, the hyperfine fields on various Fe sites have also been analyzed by 57Fe M?ssbauer effect.
