ystals of the N-type superconducting Nd2\_~CexCuO4\_~. system have been grown by a self-flux technique. In this method, excess Ce is required to obtain single crystals with optimal superconducting properties. Crystals grown by this technique show superconducting transition temperatures with onsets o
We report phase segregation based on cerium content in thick (> 70 ~tm) single crystals and a polycrystalline sample of Nd2\_xCexCuO4\_y with nominal composition x = 0.15. The crystals showed segregation into sharply defined sheets of material with different cerium concentrations. These sheets in th
