Magnetic ground state of the dimer-based hexagonal perovskite Ba $_{3}$ ZnRu $_{2}$ O $_{9}$

S. Hayashida, H. Gretarsson, P. Puphal +7

We investigate the magnetic ground state of single crystals of the ruthenium-dimer-based hexagonal perovskite Ba $_{3}$ ZnRu $_{2}$ O $_{9}$ using magnetic susceptibility and resonant i…

Investigation of spin excitations and charge order in bulk crystals of the infinite-layer nickelate LaNiO $_{2}$

S. Hayashida, V. Sundaramurthy, P. Puphal +10

Recent x-ray spectroscopic studies have revealed spin excitations and charge density waves in thin films of infinite-layer (IL) nickelates. However, clarifying whether the origin o…

Plasmon dispersion in bilayer cuprate superconductors

M. Bejas, V. Zimmermann, D. Betto +11

The essential building blocks of cuprate superconductors are two-dimensional CuO $_{2}$ sheets interspersed with charge reservoir layers. In bilayer cuprates, two closely spaced CuO$_…

Spin-orbit excitons in a correlated metal: Raman scattering study of Sr2RhO4

Lichen Wang, Huimei Liu, Valentin Zimmermann +6

Using Raman spectroscopy to study the correlated 4 $d$ -electron metal Sr $_{2}$ RhO $_{4}$ , we observe pronounced excitations at 220 meV and 240 meV with $A_{1g}$ and $B_\mathrm{1g}…

Single crystal synthesis, structure, and magnetism of Pb $_{10 - x}$ Cu $_{x}$ (PO $_{4}$ ) $_{6}$ O

P. Puphal, M. Y. P. Akbar, M. Hepting +4

The recent claim of superconductivity above room temperature in Pb $_{10 - x}$ Cu $_{x}$ (PO $_{4}$ ) $_{6}$ O with 0.9 < $x$ < 1 (referred to as LK-99) has sparked considerable interest. To minim…

Evolution of plasmon excitations across the phase diagram of the cuprate superconductor La $_{2 - x}$ Sr $_{x}$ CuO $_{4}$

M. Hepting, T. D. Boyko, V. Zimmermann +19

We use resonant inelastic x-ray scattering (RIXS) at the O $K$ - and Cu $K$ -edges to investigate the doping- and temperature dependence of low-energy plasmon excitations in La$_{2-x…
