Photoemission insights into lanthanide-based crystals

Dmitry Yu. Usachov, Georg Poelchen, Vasily S. Stolyarov +3

The interplay of strongly localized 4 $f$ electrons with itinerant spd-valence states gives rise to a wide range of correlated phenomena and properties that place lanthanide materia…

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…
