Unveiling orbital landscapes in strongly correlated bulk nickelates with $s$ -NIXS

Edgar Abarca Morales, Martin Sundermann, Brett Leedahl +10

We leverage $s$ -orbital non-resonant inelastic X-ray scattering ( $s$ -NIXS) to perform orbital imaging on three bulk rare-earth nickelates spanning a range of formal nickel valence…
