Description
We investigated the generic phase diagram of the electron doped superconductor, Nd2-xCexCuO4, using films prepared by metal organic decomposition. After careful oxygen reduction treatment to remove interstitial Oap atoms, we found that the Tc increases monotonically from 24 K to 29 K with decreasing x from 0.15 to 0.00, demonstrating a quite different phase diagram from the previous bulk one. Based on the discussion on the tremendous influence of Oap 'impurities' on superconductivity in T' cuprates, we conclude that our result represents the generic phase diagram for oxygen-stoichiometric Nd2-xCexCuO4.
