| Abstract: | A cadmium analogue of the mercury system with nominal composition CdBa2(Ca1–xYx)Cu2Oy has been synthesized. Thex=0 samples contain about 12 vol.% of the 1212 phase but are not superconducting. Thex=0.3 samples are superconducting atT on = 103 K. The EDX analysis of 18 microcrystals shows a broad cationic distribution of the different components. The observed broad superconducting transition is attributed to the variousT c of the different microcrystals. |
