Abstract
A cadmium analogue of the mercury system with nominal composition CdBa 2(Ca1-xYx)Cu2Oy has been synthesized. The x=0 samples contain about 12 voL% of the 1212 phase but are not superconducting. The x=0.3 samples are superconducting at T-on=103 K. The EDX analysis of 18 microcrysta ls shows a broad cationic distribution of the different components. Th e observed broad superconducting transition is attributed to the vario us T-c of the different microcrystals.
