Notes:
The single-phase compounds of Gd2Fe17−xGaxC2 (x=0, 1, 2, 3, 4, 5, and 6) with rhombohedral Th2Zn17-type structure were prepared by melt spinning for x≤1 and arc melting for x≥2. Their formation, structure, and magnetic properties were studied. The substitution of Ga for Fe in Gd2Fe17C2 helps the formation of the 2:17-type structure. The addition of Ga results in the increase of the lattice constants and the unit-cell volumes. The Curie temperature has a small change when x≤2, and then decreases rapidly with increasing Ga concentration. An approximately linear decrease of the saturation magnetization with x is observed when the nonmagnetic Ga atom is substituted for Fe.
