Fe-K\({}_{\beta }\) X-ray emission spectroscopy (XES) and difference spectra for BaFe2(As1−xPx)2. K\({}_{\beta }\) XES for \(x=0.00\), and 0.52 (a, b as black lines) and reference spectrum of FeCrAs (a, b as red lines). The integrated area difference (IAD) is displayed as grey line. c Summary of IADs for all the samples. d Values of local magnetic moment extracted from XES compared with theoretical estimates of the Fermi surface (FS) nesting strength. The nesting strength is calculated integrating the static susceptibility at the nesting wavevector. The error bars on the values of \({\mu }_{{\mathrm{bare}}}\) are systematic due to the normalisation and subtraction steps; thus, all the values have an error of \(\pm\)0.1 with respect to the values assumed by the parent compound. e Summary of local magnetic moment from XES (orange) and intensity of spin excitations (green) integrating the fitting from the resonant inelastic X-ray scattering (RIXS) spectra at high momenta (three highest momenta) along (H, 0) and (H, H) as a function of doping across the phase diagram of BaFe2(As1−xPx)2. In order to visualise the reciprocal redistribution of local magnetic moments and spin excitations, we represent the superconducting dome as a purple shaded area in the background. The error bars on the intensity of the spin excitations have been quantified in \(\pm\)0.1 with respect to the value of the parent compound. The fitting error is actually smaller, but the sum procedure at different q points produces a propagation of the errors, so we set a slightly higher upper boundary
