Description

We report X-ray diffraction, resistivity and Moessbauer studies on several substituted 2201 Bi cuprates, Bi2Sr2Cu1-xFexOy(O ≤ x ≤ 1) and Bi2Sr1.6La0.4Cu1-xFexOy and Bi1.6Pb0.4Sr1.6La0.4Cu1-xFexOy(O ≤ x ≤ 0.04). The first series is not superconducting and a new phase appears for x = 1. For La substituted samples, Tc increases up to 35K and decreases strongly with x. All Moessbauer spectra were fitted well with four quadrupole doublets, with relative population depending on samples. (orig.)
