摘要：
The effect of cadmium (Cd) substitution in the Bi, Sr and Ca sites of the Bi-Sr-Ca-Cu-O superconducting system has been studied. An optimum level of Cd doping is found to exist such that further addition of Cd causes a decrease in the transition temperature. Electrical resistance measurements show a maximum T(c) (offset) of 90.7, 87 and 86 K for the samples with nominal composition Bi1.4Cd0.6Sr2CaCu2Oy, Bi2Sr1.7Cd0.3CaCu2Oy and Bi2Sr2Ca0.9Cd0.1Cu2Oy, respectively.
