Abstract
Abstract The system samarium-cobalt has been studied over the whole concentration range. The following compounds were observed: Sm 3 Co, Sm 9 Co 4 , SmCo 2 , SmCo 3 , Sm 2 Co 7 , SmCo 5 , α-Sm 2 Co 17 and β-Sm 2 Co 17 . The lattice parameters for these compounds have been determined, and, with the exception of Sm 9 o 4 , the structure type is given. Large homogeneity regions have been observed at higher temperatures for the compounds SmCo 5 and Sm 2 Co 17 . From the results of X-ray diffraction, thermo-analysis and metallography a tentative phase diagram has been constructed.
