The superconducting and magnetic properties of the compounds La1.85Sr0.15Cu1-xFexO4 and YBa2(Cu1-xFex)3O7-y with 0<x<0.1 are presented. The Fe substitution in the La-Sr compound rapidly depresses Tc, extrapolating to Tc=0 for x∼0.02. However, Tc is depressed much less rapidly in the Y-Ba compound, extrapolating to 0 K for x∼0.16. Mössbauer spectroscopy and magnetic data have been obtained to give information on the magnetic and structural properties of these materials. The results are compared with those for other dopants, both magnetic and non-magnetic, in the oxide superconductors. © 1987.
