Zero resistance at 107 K in the (Bi,Pb)-Ca-Sr-Cu oxide system

Journal Article · · Phys. Rev. B: Condens. Matter; (United States)

The 110-K superconducting transition in the Bi-Ca-Sr-Cu-O system has been observed by many researchers. However, not even a filamentary path has been obtained connecting these regions in multiphase, polycrystalline samples. We have achieved zero resistance at temperatures exceeding 100 K in several samples by adding Pb to the system. The highest value we have observed is T/sub c//sub ,zero/ = 107 K for Bi/sub 1.8/Pb/sub 0.2/Ca/sub 2/Sr/sub 2/Cu/sub 3/O/sub y/.
