Antiferromagnetism-superconductivity competition in electron-doped cuprates triggered by oxygen reduction

P. Richard, M. Neupane, Y. -M. Xu +5

We have performed a systematic angle-resolved photoemission study of as-grown and oxygen-reduced Pr${}_{2-x}$Ce${}_x$CuO${}_4$ and Pr${}_{1-x}$LaCe${}_x$CuO${}_4$ electron-doped cuprates. In…
