Zero-resistivity superconducting transition at 120 K in the BiPbSrCaCuO system

Electrical resistance, magnetic susceptibility and powder X-ray diffraction patterns of (Bi 0.7Pb 0.3)SrCaCu 1.5O y pellet samples subjected to an extra thermal annealing cycle have been investigated. Zero-resistivity transition of 120 K has been attained in these samples. Rise in T c is attributed...

Zusammenfassung:Electrical resistance, magnetic susceptibility and powder X-ray diffraction patterns of (Bi 0.7Pb 0.3)SrCaCu 1.5O y pellet samples subjected to an extra thermal annealing cycle have been investigated. Zero-resistivity transition of 120 K has been attained in these samples. Rise in T c is attributed to the change in microstructure of the samples due to the extra thermal annealing.
