Polycrystalline Pb2Sr2Yl\_xCaxCu3Os+ 8 (PSYCCO) samples have been prepared without precursor (x=0.3-0.6). The samples exhibit a metallic normal-state conductivity, and the highest To(R=0 ) achieved is 70K. Regarding anisotropy, SQUID-magnetometry demonstrates the intermediate position of PSYCCO betw
The dependence on the oxygen concentration of normal and superconducting properties of ceramic samples of Pb2Sr2Y~ \_xCaxCu3Os+a has been investigated in the composition range of 0 \_< x< 0.5 and 0\_< fi< 2. The superconductivity in each sample with different x is suppressed with increasing ~, which
