SUPERCONDUCTIVITY IN GLASSY Bi-Sr-Ca-Cu-O SYSTEM
-
Abstract
To explore high Tce in Bi-Sr-Ca-Cu-O system, many different nominal compositions have been investigated. Zero resistance temperature Tce as high as 105K and only one sharp 3uperconducting transition in a.c. susceptibility measurement has been observed in the nominal composition Bi2Sr2Ca3Cu4Oy by using the method of crystallization from glassy Bi-Sr-Ca-Cu-O at 875°C for above 50h.
