摘要：

The gadolinium-cobalt system has been investigated over the whole concentration range by means of X-ray diffraction, thermoanalysis, and metallography. Eight intermetallic compounds have been observed: Gd3Co, GdxCo (with x≈ 7 4), Gd4Co3, GdCo2, GdCo3, Gd2Co7, GdCo5 and Gd2Co17. The compounds Gd2Co7 and Gd2Co17 show a structure transformation. For all compounds except GdxCo the lattice constants and the structure type are given. The compounds GdCo5 and Gd2Co17 possess large homogeneity regions at elevated temperatures. For GdCo5, the variation of the saturation moment and the coercive force within the homogeneity region have been studied. High values for the coercive force (up to 43,000 Oe) have been observed for some of the other gadolinium-cobalt compounds. © 1969.
