对Sm2Fe17-xMoxC化合物的磁性和M?ssbauer效应进行了系统的研究,少量Mo对Fe的有序替代,导致化合物的居里温度稍有增加,磁晶各问异性和内禀矫顽力明显增强,并且都在Mo浓度在x=0.6附近出现峰值,M?ssbauer谱分析表明,化合物内禀性质的变化与Mo原子择优占居结构中的18h晶位有关。Intrinsic properties and M?ssbauer effects of the compounds in Sm2Fe17-xMoxC system were investigated. The substitution of Mo for Fe led to an increase of Tc, HAand iHc with a maximum at about x = 0.6. M?ssbauer analysis showed that the Mo atoms preferentially occupied the 18h sites in the Th2Zn17 structure.
