Strong Superexchange in a d9−δ Nickelate Revealed by Resonant Inelastic X-Ray Scattering

The discovery of superconductivity in a d9−δ nickelate has inspired disparate theoretical perspectives regarding the essential physics of this class of materials. A key issue is the magnitude of the magnetic superexchange, which relates to whether cuprate-like high-temperature nickelate superconduct...
