摘要：

SmTiFe11-xCox (0&lex&le11) alloys were synthesized and studied by X-ray, SEM, EDXS and magnetometry at fields up to 90 kOe in the temperature range of 4.2-1100 K. The present investigation shows that replacement of Fe by Co in SmTiFe11-xCox beyond x 2 leads to the appearance of a considerable amount of extraneous phases (primarily of 2:17 stoichiometry). Present results are in contrast with those of K. Ohashi et al. who reported the SmtiFe11-xCox compounds to be stable up to x=11. In view of the absence of ThMn12-type of compound in the binaries, Sm-Fe, Sm-Ti, Sm-Co, Ti-Fe, Ti-Co or Co-Fe system, the presence of the pseudoternary compounds, SmTiFe11-xCox (x<2) are most interesting, as they open new possibilities for novel magnetic materials.
