Therefore, (nonresonant) Kβ1,3 and valence-to-core X-ray emission spectroscopy as well as resonant 1s2p X-ray emission spectroscopy were utilized. First, the study of laser-heated FeCO3 at about 80 GPa results [...] could be assigned to Fe4C4O13. Second, the study on cold compressed Fe2O3 verifies a two-step spin transition from α- via ζ- to Θ-Fe2O3. Moreover, resonant X-ray emission spectroscopy measurements support [...] the interpretation of Kβ1,3-spectra in the future. Additionally, the setup for spectroscopic measurements was significantly improved with reduced data acquisition times of Kβ1,3 X-ray emission spectroscopy …
