A novel method for mapping the local spin and orbital nature of the groundstate of a system via corresponding flip excitations in both sectors isproposed based on angle resolved resonant photoemission and related diffractionpatterns, presented here for the first time via an ab-initio modified one-steptheory of photoemission. The analysis is done on the paradigmatic weakitinerant ferromagnet bcc Fe, whose magnetism, seen as a correlation phenomenongiven by the coexistence of localized moments and itinerant electrons, and thenon-Fermi liquid behaviour at ambient and extreme conditions both remainunclear. The results offer a real space imaging of local pure spin flip andentangled spin flip-orbital flip excitations (even at energies where spin fliptransitions are hidden in quasiparticle peaks) and of chiral, vortex-likewavefronts of excited electrons, depending on the orbital character of thebands and the direction of the local magnetic moment. Such effects, mediated bythe hole polarization, make resonant photoemission a promising tool to performa full tomography of the local magnetic properties of a system with a highsensitivity to localization/correlation, even in itinerant or macroscopicallynon magnetic systems.
