Robust Superconductivity in Infinite-Layer Nickelates.

ABSTRACT: The recent discovery of nickelate superconductivity represents an important step toward understanding the four-decade mastery of unconventional high-temperature superconductivity. However, the synthesis of the infinite-layer nickelate superconductors shows great challenges. Particularly, surface capping layers are usually unitized to facilitate the sample synthesis. This leads to an important question whether nickelate superconductors with d⁹ configuration and ultralow valence of Ni¹⁺ are in metastable state and whether nickelate superconductivity can be robust? In this work, a series of redox cycling experiments are performed across the phase transition between perovskite Nd_0.8Sr_0.2NiO₃ and infinite-layer Nd_0.8Sr_0.2
