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…

UCd $_{11}$ : A strongly localized 5 $f^{3}$ material

Martin Sundermann, Naoki Ito, Daisuke Takegami +11

UCd $_{11}$ is an antiferromagnetic uranium intermetallic compound ( $T_{N}$ = 5.3K) with enhanced electron mass and uranium-uranium spacings nearly twice the Hill limit, suggest…

Stabilization of U 5 $f^{2}$ configuration in UTe $_{2}$ through U 6d dimers in the presence of Te2 chains

Denise S. Christovam, Martin Sundermann, Andrea Marino +16

We investigate the topological superconductor candidate UTe $_{2}$ using high-resolution valence-band resonant inelastic x-ray scattering at the U $M_{4, 5}$ -edges. We observe atomic-l…

Charge transfer energy in iridates: a hard x-ray photoelectron spectroscopy study

D. Takegami, D. Kasinathan, K. K. Wolff +20

We have investigated the electronic structure of iridates in the double perovskite crystal structure containing either Ir $^{4 +}$ or Ir $^{5 +}$ using hard x-ray photoelectron spectro…

Impact of Fe substitution on the electronic structure of URu $_{2}$ Si $_{2}$

Martin Sundermann, Andrea Amorese, Daisuke Takegami +9

The application of pressure as well as the successive substitution of Ru with Fe in the hidden order (HO) compound URu $_{2}$ Si $_{2}$ leads to the formation of the large moment antiferr…

Dual nature of 5 $f$ electrons in the isostructural UM $_{2}$ Si $_{2}$ family: from antiferro- to Pauli paramagnetism via hidden order

Andrea Amorese, Martin Sundermann, Brett Leedahl +16

Using inelastic x-ray scattering beyond the dipole limit and hard x-ray photoelectron spectroscopy we establish the dual nature of the U $5 f$ electrons in UM $_{2}$ Si $_{2}$ (M = Pd, Ni,…
