摘要：

New Pb based layered superconducting cuprates (Pb0.5Cd0.5)(Sr(0.9)R(0.1))(2)(Rb-0.7'Ce-0.3)(2)Cu2Oy with (R,R')=(Eu,Gd), (Eu,Dy) and (Nd,Gd), have been successfully synthesized. The structure of (Pb,Cd)(Sr,Eu)(2)(Gd,Ce)(2)Cu2Oy is determined using XRD data. The X-ray powder diffraction pattern can be indexed by the tetragonal structure with lattice parameters a=3.8250 Angstrom, c=29.2235 Angstrom and space group of I4/mmm. The effects of synthesis conditions on are studied and a T-c(onset) of 26 K is obtained by resistance measurements. It is isostructural to the superconductor (Pb,Cu)(Sr,Eu)(2)(Eu,Ce)(2)Cu2Oy.
