Structure of the Fe-doped high-temperature superconductors Y#71Ba#72Cu#73O#y#3 and Bi#72Sr#72Ca#71Cu#72O#y#3

YBa#72(Cu#71#7d#xFe#x)#73O#y and Bi#72Sr#72Ca#71(Cu#71#7d#xFe#x)#72O#y were examined by resistivity measurements, XRD, and Moessbauer experiments to understand influence of Fe on structure of the perovskites. The concentration dependence of Fe substitution and results of annealing experiments are co...

Description
Summary:YBa#72(Cu#71#7d#xFe#x)#73O#y and Bi#72Sr#72Ca#71(Cu#71#7d#xFe#x)#72O#y were examined by resistivity measurements, XRD, and Moessbauer experiments to understand influence of Fe on structure of the perovskites. The concentration dependence of Fe substitution and results of annealing experiments are consistent with proposed model.
