Revealing the site selective local electronic structure of Co $_{3}$ O $_{4}$ using $2 p 3 d$ resonant inelastic X-ray scattering

Ru-Pan Wang, Meng-Jie Huang, Atsushi Hariki +9

We investigate mixed-valence oxide Co $_{3}$ O $_{4}$ using Co $2 p 3 d$ resonant inelastic X-ray scattering (RIXS). By setting resonant edges at Co $^{2 +}$ and Co $^{3 +}$ ions, the $dd$ excit…

Damping of spinful excitons in LaCoO $_{3}$ by thermal fluctuations: Theory and experiment

Atsushi Hariki, Ru-Pan Wang, Andrii Sotnikov +7

We present Co $L_{3}$ -edge resonant inelastic x-ray scattering (RIXS) of bulk LaCoO $_{3}$ across the thermally-induced spin-state crossover around 100~K. Owing to a high energy resolut…

Excitonic dispersion of the intermediate-spin state in LaCoO $_{3}$ revealed by resonant inelastic X-ray scattering

Ru-Pan Wang, Atsushi Hariki, Andrii Sotnikov +9

More than 50 years ago the electron-hole attraction was proposed to drive narrow gap semiconductors or semimetals to a new phase, the excitonic insulator. The experimental proof of…

Coulomb correlations intertwined with spin and orbital excitations in LaCoO $_{3}$

K. Tomiyasu, J. Okamoto, H. Y. Huang +11

We carried out temperature-dependent (20 - 550 K) measurements of resonant inelastic X-ray scattering on LaCoO $_{3}$ to investigate the evolution of its electronic structure across t…
