It is found that the solid solubility of Ce in Nd 2-x Ce x CuO 4±ı is limited up to x = 0.2. A semiconductor to metallic transition is observed at 600 • C in d.c. conductivity data, which coincides with a transition in temperature-dependent area-specific resistance (ASR). Nd 1.8 Ce 0.2 CuO 4±ı is th
