Among the almost-single phase samples, asample with the nominal composition of (Pb0.75P0.25)Sr2(Y0.4Ca0.6)Cu2O z was a superconductor with the highest T c of 38K in the system. Recently, we have been investigating on substitution effect of Ba for Sr on superconductivity in the (Pb0.75P0.25)(Sr2−x Ba x )(Y0.4Ca0.6)Cu2O z system. As a result, it is found that the almost-single 1212 phase samples are obtained in the composition area of 0.0≤x≤0.4. In this area, with increase of x, the lattice parameters a,c and the cell volume V are found to be gradually increasing. This finding can be considered to show that larger Ba2+ ions certainly occupied the Sr-sites in the sample. However, we obtain such interesting results as that the T c value is not so enhanced by the substitution in comparison with that of the sample of x=0.0, and that the maximum value of T c was 40K for x=0.2 and 0.3 at the best.
