Abstract

The effect of Cd substitution for Ca in Bi₂Sr₂Ca₂Cu₃O_y has been studied using the rapid-quenching-after-rapid-melting technique. The zero resistivity temperature T_c(endpoint) increased and tailing of transition vanished with increased doping of Cd. The film with the composition Bi₂Sr₂Ca_1.6Cd_0.4Cu₃O_y exhibited a T_c(endpoint) value of 87 K without tail. Further substitution of Cd for Ca brought about lowering in the T_c until finally no superconductivity transition was shown above 20 K, because a semiconducting phase with c₀=2.5 nm formed instead of a c₀=3.0 nm phase.
