摘要：
A new layered superconducting cuprate RuSr2(Gd2-xCex)Cu2Oz with a T-c(onset) of 30 K determined by resistance measurements has been synthesized. The crystal structure is determined by X-ray powder diffraction and Rietveld analysis. The compound RuSr2(Gd2-xCex)Cu2Oz has a tetragonal symmetry with lattice parameters a - 3.8470(5), c = 28.649(1) Angstrom for x = 0.6 and a space group of I-4/mmm. It is isostructural to the superconductor TaSr2(Ln,Ce)(2)Cu2Oz.
