Re-entrant unconventional superconductivity induced by rare-earth substitution in Nd1-x Eu x NiO2 thin films

Abstract High temperature superconductivity is typically associated with strong coupling and a large superconducting gap, yet these characteristics have not been demonstrated in the nickelates. Here, we provide experimental evidence that Eu substitution in the spacer layer of Nd1-x Eu x NiO2 (NENO)...
