Fig. 1: Overview of the crystal structure, experimental configuration, and Cu L3 X-ray absorption spectroscopy (XAS) and resonant inelastic X-ray scattering (RIXS) data.

Fig. 1

a Cu2OSeO3 unit cell (a = 8.925 Å). The orange dashed line highlights the magnetic tetrahedron unit. b Cu L3 XAS spectrum in terms of total fluorescence yield (TFY), at T = 45 K. TFY* is the spectrum after correction for self-absorption and saturation effects. c RIXS energy map with linear color scale for the intensity, also at T = 45 K. The thin solid line displays the partial fluorescence yield (PFY) signal, obtained integrating the RIXS spectra up to 10 eV. The inset in panel b displays the sample orientation used for these measurements, with [100] and [01-1] axes lying within the scattering plane. Incoming π polarized x-rays were used for all measurements.
