摘要：
Phase formation as well as the influence of Nb and Zr in the structural and magnetic properties in a series of intermetallic compounds with nominal composition Gd8Fe86Nb6-xZrx (x= 1.5, 3.0, 4.5) were studied. No serious crystallographic effects for the change in stoichiometry were identified. The major phase formed was found to be the hexagonal 2:17 compound. Curie temperature is enhanced compared to that of the parent Gd2Fe17 compound and increases with increasing Nb. Magnetization measurements were analyzed by Sucksmith-Thompson method and the anisotropy field and constants at room temperature and 110 K were calculated.
