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-T{sub c} phase forms has been reported in their early paper, where the temperature of zero resistance was 107 K. Recently, they 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 Bi{sup 1.6}Pb{sup 0.4}Sr{sup 2}Ca{sup 2}Cu{sup 2+x}O{sup y} system (x = 0, 0.4, 0.8, 1.2, and 1.6).
