Title: Synthesis conductivity, and X-ray photoelectron spectrum of Bi sub 2 Sr sub 2 Cu sub 7+X. A new ternary bismuth-oxide system exhibiting metallic conductivity

Abstract

The preparation and some of the properties relating to the superconductive state of the newly discovered ternary bismuth oxides, Bi{sub 2}Sr{sub 2}Cu{sub 2}O{sub 7+x}, are described. Conductivity behavior ranging from semiconductive to metallic is observed when four-probe. AC resistivity measurements are carried out on pressed pellet specimens that have been annealed under different conditions. From a determination of the total oxygen present by an iodometric titration, it was found that metallic conductivity was associated with a higher oxygen content. An X-ray photoelectron experiment was carried out in order to determine whether bismuth or copper was present as the mixed-valent species. The XPS spectrum of the Bi 4f orbital electrons in the oxides was nearly identical to that observed in Bi{sub 2}O{sub 3}, with no evidence of any Bi{sup 5+}. 8 refs., 3 figs.
