High-resolution valence band RIXS at the actinide M-edges
Martin Sundermann, Henrik Hahn, Denise S. Christovam +6
Understanding the electronic structure of actinide materials is crucial for both fundamental research and nuclear applications. The partially filled 5f shells exhibit complex behav…
UTe: a narrow band superconductor
Martin Sundermann, Takaki Okauchi, Naoki Ito +10
We investigate the nature of the 5 electrons in the unconventional odd-parity superconductor UTe, focusing on the degree of covalency, localization versus itinerancy, and do…
Quantifying the U covalence and degree of localization in U intermetallics
Andrea Marino, Denise S. Christovam, Daisuke Takegami +17
A procedure for quantifying the U electrons' covalence and degree of localization in U intermetallic compounds is presented. To this end, bulk sensitive hard and soft x-ray ph…
Stabilization of U 5 configuration in UTe 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 using high-resolution valence-band resonant inelastic x-ray scattering at the U -edges. We observe atomic-l…
Linear dichroic x-ray absorption response of Ti-Ti dimers along the axis in TiO upon Mg substitution
M. Okawa, D. Takegami, D. S. Christovam +9
Corundum oxide TiO shows the metal-insulator transition around 400-600 K accompanying the nearest Ti-Ti bond ( singlet state) formation along th…
Fe substitution in URuSi: singlet magnetism in an extended Doniach phase diagram
Andrea Marino, Denise S. Christovam, Chun-Fu Chang +13
The application of pressure as well as the successive substitution of Ru with Fe in the hidden order (HO) compound URuSi leads to the formation of the large moment antiferr…
