Probing La-based nickelates with Ni 1 $s$ core-level photoelectron spectroscopy

Daisuke Takegami, Naoki Ito, Koto Fujinuma +15

We present a comparative Ni core level photoemission study of La $_{3}$ Ni $_{2}$ O $_{7}$ , Nd $_{3}$ Ni $_{2}$ O $_{7}$ , and LaNiO $_{3}$ using both the Ni $2 p$ and the Ni $1 s$ . We address the challenges…

Yb 4f-Ta 5d Hybridization and Valence Evolution in Tetragonal Tungsten Bronze Ba(3-x)YbxTa5O15

Daisuke Takegami, Haruki Takei, Masato Yoshimura +2

Here we investigate the electronic structure of the tetragonal tungsten bronze Ba $_{3 - x}$ Yb $_{x}$ Ta $_{5}$ O $_{15}$ by making use of hard x-ray photoemission spectroscopy. The core lev…
