Thin films showing zero resistivity at 103 K were prepared by annealing a Bi‐Sr‐Ca‐Cu‐O film in PbO vapor. Electron probe microanalysis indicated that Pb ions were doped into the film materials up to the amount of maximum solubility. However, experiments on Bi‐Sr‐Ca‐Cu‐O bulks showed that excess amounts of Pb ions formed Ca 2 PbO 4 with decomposition of superconducting phases.
