Light rare-earth metals are not assumed to form compounds of the CaCu/sub 5/-type structure with iron. When zirconium was not added, the Th/sub 2/Zn/sub 17/-type rhombohedral structure existed in the samples of nominal composition SmFe/sub 5/ and SmFe/sub 7/. Samples of nominal composition (Sm/sub 1-//sub x/Zr/sub x/)Fe/sub 5/ and (Sm/sub 0.65/Zr/sub 0.35/)Fe/sub y/ were studied by x-ray diffraction and thermomagnetic analyses. Thermomagnetic analyses showed the existence of a new phase besides Sm/sub 2/Fe/sub 17/. X-ray diffraction analyses showed the new phase has a CaCu/sub 5/-type structure. Lattice parameters and Curie temperatures of these samples were measured.
