From: The nature of ferromagnetism in the chiral helimagnet Cr1/3NbS2
Resonant photoemission spectra measured across the a, b Cr L3 and c, d Nb M5 absorption edges using linear horizontal photon polarization. Intensity maps (a, c) and selected photoemission spectra generated across the b Cr and d Nb x-ray absorption edge (XAS) shown in the inset. Spectra denoted 1–4 in a, c are taken through the Cr and Nb resonance, respectively. Hatched area in b, d denotes the difference between spectra taken on resonance (1–4) and off resonance (0).
