Photoelectron Spectroscopy Study of U-Te Thin Films: A Unified Perspective of Hybridization Effects across Compositions
E. A. Tereshina-Chitrova, S. G. Alex, O. Koloskova +6
Uranium tellurides span magnetic and superconducting ground states, yet systematic electronic-structure information across the U-Te series remains scarce. In this study, we perform…
Electronic Structure of UGe Thin Films from Photoelectron Spectroscopy
Sonu George Alex, Oleksandr Romanyuk, Ivan Zorilo +7
Uranium digermanide UGe, the first ferromagnetic superconductor, represents a key composition in the U-Ge system dominated by U-5 states. To examine the impact of controlled…
Spin and Orbital Magnetism in UH2 Thin Films Studied by X-ray Magnetic Circular Dichroism
Evgenia A. Tereshina-Chitrova, Mykhaylo Paukov, Oleksandra Koloskova +8
Uranium dihydride UH2 is a metastable phase unknown in bulk form but accessible through thin-film synthesis. We prepared UH2 films by reactive dc sputtering on CaF2(001) or Si(001)…
Magnetic anisotropy and intermediate valence in CeCo ferromagnet
Alexander B. Shick, Evgenia A. Tereshina-Chitrova
The intermediate valence of Ce in CeCo challenges standard density functional theory (DFT) and static DFT+ approaches, which fail to capture its magnetic properties. By comb…
High-field ultrasound study of elastic constants and possible magnetic symmetry transformations in UO2
E. A. Tereshina-Chitrova, L. V. Pourovskii, S. Khmelevskyi +2
In this study, we probe the coupling between magnetism and lattice dynamics in UO2, a 3k antiferromagnet that undergoes magnetic ordering below its Neel temperature (TN) of 30.8 K.…
