N2 - We report on the structural, magnetic, and Raman-scattering studies of double-perovskite structure Sr2 Y Ru1-x Cux O6-δ systems made by systematic synthesis processes with various numbers of doping concentrations and sintering temperatures. We observed different behaviors resulting from the different thermal treatments. In particular, superconductivity in Cu-doped Sr2 YRu O6 has been observed only for partially melted ceramic materials. We show that superconductivity is associated with the 1:2:3 phase (Y Sr2 Cu3 Ot), similar to that of Y-Sr-Cu-O samples sintered at high temperature.
