Abstract
In the Pb-doped Bi-Sr-Ca-Cu-O system, optimization of the composition and heat treatment conditions at which a greater amount of the high-Tcphase forms has been reported in our early paper [1], where the temperature of zero resistance was 107K. Recently, we have achieved zero resistance at 117 K and observed an a.c. susceptibility step at around 150 K by changing the Cu composition in the Bi1.6Pb0.4Sr2Ca2Cu2+xOy system (x=0, 0.4, 0.8, 1.2, and 1.6).
