Fig. 2

XES data of FePS3 and FePSe3 showing the spin-crossover of Fe2+ under compression. a, b Fe K β XES of FePS3 and FePSe3 as a function of applied pressure. Inset of a shows the XES process from 3p to 1s orbital, and the relationship with 3d spin state. c The derived IAD values and corresponding magnetic moment numbers of FePS3 and FePSe3 as a function of pressure. Error bars represent ± S.D. estimated for the IAD analyses
