Valency, charge-transfer, and orbital-dependent correlation in bilayer nickelates Nd3Ni2O7
Daisuke Takegami, Takaki Okauchi, Edgar Abarca Morales +14
We examine the bulk electronic structure of Nd3Ni2O7 using Ni 2p core-level hard x-ray photoemission spectroscopy combined with density functional theory + dynamical mean-field the…
