Doping of Pb ions inot Bi-Sr-Ca-Cu-O thin films from PBO vapor

This paper reports thin films showing zero resistivity at 103 K 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 t...

Zusammenfassung:	This paper reports thin films showing zero resistivity at 103 K 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{sub 2}PbO{sub 4} with decomposition of superconducting phases.
