The structural and magnetic properties of melt-spun Co-Ge intermetallic alloys have been investigated over a wide range of compositions Co62+xGe38−x (x = 0, 1, 2, 3, 4, 4.7, 8 and 18). The research is practically motivated by inconsistencies in the literature data regarding phase equilibria in the Co-rich part of the Co-Ge phase diagram. We resolve these contradictions by showing that the structural and magnetic properties of Co62+xGe38−x melt-spun alloys depend on the cooling rate, the composition, and, as a result, on the lattice parameters of the phases present. A new orthorhombic phase with a high Curie temperature of 805 K has been observed and reported for the first time.
