The crystallographic structure and magnetic properties of Sm{sub 2}(Fe{sub 1{minus}{ital x}}Co{sub {ital x}}){sub 17}C with {ital x} equal to 0.0, 0.1, 0.2, 0.3, 0.4, 0.7, and 1.0, and Y{sub 2}(Fe{sub 1{minus}{ital x}}Co{sub {ital x}}){sub 17}C with {ital x} equal to 0.0, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, and 1.0 have been investigated. They crystallize in the rhombohedral Th{sub 2}Zn{sub 17}-type structure or the hexagonal Th{sub 2}Ni{sub 17}-type structure. The Curie temperatures increase with increasing cobalt content and the saturation magnetizations reach a maximum at {ital x}=0.3. All Sm{sub 2}(Fe{sub 1{minus}{ital x}}Co{sub {ital x}}){sub 17}C compounds have an easy axis, but the anisotropy fields have a dependence on cobalt content. Both Y{sub 2}Fe{sub 17}C and Y{sub 2}Co{sub 17}C have an easy plane. However, an easy axis is found in a concentration range with 0.4{lt}{ital x}{lt}0.9 for the substituted Y{sub 2}(Fe{sub 1{minus}{ital x}}Co{sub {ital x}}){sub 17}C compounds.
