Abstract: We report the observation of superconductivity for samples with T ′ phase structure in the Gd2-x-y La x Ce y CuO z system. The samples exhibiting superconductivity lie in a limited composition range. Among them, the sample with the composition of Gd0.72La1.15Ce0.13CuO z showed the maximum superconducting onset temperature of about 12 K and the maximum zero resistivity temperature of 6.5 K. The sample was of a single T ′ phase with the lattice parameters of a=0.3969 nm and c=1.220 nm by X-ray diffraction analysis.
