    Abstract: A series of mixed ruthenium-copper oxides of general formulae Sr2Y(Ru1-xCux)O6 x=0.05, 0.10, 0.15 were prepared by high temperature synthesis. Transport and specific heat measurements at low temperatures showed these materials to be superconducting with Tc of approximately 24K and to have magnetic transitions. High-resolution neutron powder studies have been undertaken to determine the crystallographic structure and magnetic ordering present in the samples. The materials were found to be single phase P21/n with a=5.7602 Å, b=5.7795 Å, c=8.1506 Å and 90.313° for x=0.05 samples. The structure is related to that of the parent compound with additional ruthenium-copper ordering. In addition to the structural peaks, antiferromagnetic peaks were observed at temperatures below 28K confirming the magnetic order.
