Description
A new copper oxide based superconductor is reported based on the ordered interleaving of NbO6 or TaO6 octahedra between the apices of copper oxide pyramids. Good bulk superconductivity is observed for only a narrow range of temperatures, annealing times and cooling rates. The relatively low Tc of the prototype compound Sr2Nd1.5Ce0.5NbCu2O10-δ, may be due to the presence of the insulating NbO6 layers or the wide (Nd, Ce)2O2 layers which separate the CuO2 planes.
