Crystal structures and magnetic properties of Au-Mn-Sb alloys have been investigated by means of X-ray and magnetic analyses. It has been found that an intermetallic AuMnSb compound of the C1b type exists in the Au-Mn-Sb system and forms a solid solution in the narrow compositional range which has lattice parameters of about 6.368∼6.3775 Å at room temperature. The AuMnSb compound has a lattice parameter of 6.373 Å at room temperature, and its reciprocal susceptibility satisfies the Curie-Weiss law. From this relationship, the paramagnetic effective Bohr magneton number per Mn atom and the paramagnetic Curie temperature have been determined to be 5.98 and 98°K, respectively.
