MAGNETIC PROPERTIES AND M?SSBAUER STUDY OF THE Sm 2 Fe 17-x Mo x C COMPOUNDS

Intrinsic properties and M?ssbauer effects of the compounds in Sm 2 Fe 17-x Mo x C system were investigated. The substitution of Mo for Fe led to an increase of T c , H A and i H c with a maximum at about x = 0.6. M?ssbauer analysis showed that the Mo atoms preferentially occupied the 18h sites in the Th 2 Zn 17  structure.
