Generic phase diagram of "electron-doped" T' cuprates
Osamu Matsumoto, Aya Utsuki, Akio Tsukada +3
We investigated the generic phase diagram of the electron doped superconductor, Nd2-xCexCuO4, using films prepared by metal organic decomposition. After careful oxygen reduction tr…
Reduction dependence of superconductivity in undoped T' cuprates
Osamu Matsumoto, Aya Utsuki, Akio Tsukada +3
We have recently achieved superconductivity in undoped T'-RE2CuO4 (RE: Pr, Nd, Sm, Eu, and Gd), using epitaxial thin films by metal organic decomposition. The key recipes to achiev…
Superconductivity in undoped T' cuprates with Tc over 30 K
Osamu Matsumoto, Aya Utsuki, Akio Tsukada +3
Undoped cuprates have long been considered to be antiferromagnetic insulators. In this article, however, we report that superconductivity is achieved in undoped T'-RE2CuO4 (RE = Pr…
Superconductivity in undoped T'-RE2CuO4 with Tc over 30 K
O. Matsumoto, A. Utsuki, A. Tsukada +3
In this article, we report the superconductivity in T'-RE2CuO4 (RE = Pr, Nd, Sm, Eu, and Gd), which have been for a long time believed as a Mott insulator. Our discovery was achiev…
