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}…
