Magnetism of the alternating monolayer-trilayer phase of LaNiO
Rustem Khasanov, Thomas J. Hicken, Hubertus Luetkens +9
Understanding the magnetic ground state of Ruddlesden-Popper nickelates is crucial, as these materials exhibit superconductivity under high pressure and host competing electronic o…
Comparative Raman study of Ruddlesden-Popper nickelates and the monolayer-trilayer polymorph
Vignesh Sundaramurthy, Abhi Suthar, Pascal Puphal +12
Ruddlesden-Popper (RP) nickelates have attracted intense interest following the discovery of superconductivity in several members of the series, including bilayer (BL) LaNi…
Uniaxial strain tuning of polar lattice vibrations in KTaO and SrTiO
I. Khayr, N. Somun, S. Hameed +11
The interplay of electronic and structural degrees of freedom is a prominent feature of many quantum materials and of particular interest in systems with strong ferroelectric fluct…
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…
Evolution of spin excitations in superconducting LaCaCuO from the underdoped to the heavily overdoped regime
S. Hameed, Y. Liu, M. Knauft +8
We investigate high-energy spin excitations in hole-doped LaCaCuO films across a broad Ca doping range using resonant inelastic x-ray scatteri…
Lattice dynamics of the infinite-layer nickelate LaNiO
Shohei Hayashida, Vignesh Sundaramurthy, Wenfeng Wu +8
Infinite-layer (IL) nickelates have rapidly emerged as a new class of superconductors. However, due to the technical challenges of their topotactic synthesis, they have so far been…
