Abstract
A novel series of Bi-1212 superconducting cuprates (Bi1-xCdx)Sr2(Y1-yC ay)Cu2Oz has been discovered in this work. The structure was suggested to be that of (Bi, Cu)Sr2yCu2Oz with Cd2+ ions substituting into the Cu2+ sites in the rock-salt-type (Bi, Cu)O layers. The superconductivi ty was induced in the as-prepared samples by treatment under oxygen pr essure of 10 atm at 800-degrees-C with a composition of (Bi0.27Cd0.73) Sr2(Y0.7Ca0.3)Cu2Oz. The zero-resistivity temperature is 26 K.
