“…The shell and the chemical selectivity of the RXS technique allows to probe directly the 3d and the 4p shells of transition metals (K-edge), the 4f or the 5d shells of lanthanides (L-edges), and the 6d or the 5f shells of actinides (L-and M-edges). The azimuthal dependence is a method which 03002-p. 35 Collection SFN directly probes the symmetries of the tensors involved in resonant scattering amplitudes by measuring the diffracted x-ray linear polarization upon rotating the sample around the scattering vector.…”

Abstract. The aim of these notes is to introduce the experimental methods and theoretical works in the domain of magnetic and resonant x-rays scattering on single crystals to investigate the electronic and magnetic long range order in strongly correlated electron systems. We highlight the role of the x-rays polarization analysis and control to determine the magnetic structure of materials and, more generally, the electronic long range order parameters responsible for the phase transitions.

“…Les techniques basées sur les rayons X (RX) polarisés produits par le rayonnement synchrotron et appliquées dans le domaine du magnétisme, utilisent en général trois types d'interactions fondamentales photon-électron (explicitées dans l'encadré 2, p. 59) : (i) la diffusion de Thomson ; (ii) l'interaction résonnante ; (iii) la diffusion magnétique non résonnante. Cette dernière est la plus proche de la diffraction magnétique de neutrons, car elle dépend directement de l'interaction du photon avec les moments de spin et orbitaux des électrons de valence [10].…”

“…The resonant scattering amplitudes are related to matrix elements of multipole moments operators between the initial state and intermediate unoccupied electronic states. Classifications of the transition matrix elements have been achieved [18][19][20] based on their symmetry properties under space-inversion, rotation and time reversal. Realistic calculations of the energy dependence near the absorption edges can now be obtained through efficient computer packages and ab-initio electronic band calculations [23].…”

Abstract. The International Conference on Anomalous Scattering held in Malente, Germany, in 1992 examined the broad issue of 'dispersion or resonant scattering' for X-rays. The significant aspects discussed at that time included: the evaluation of X-ray scattering factors, the role of local broken symmetries and the application to structure determinations, the impact on magnetic X-ray scattering, but also resonant Raman scattering and nuclear resonant scattering. However, many aspects of resonant elastic X-ray scattering (REXS) were still being revealed and soon it was realised that new productive paths of research would open up. In the last two decades, applications have developed thanks to concurrent developments in X-ray instrumentation and theoretical approaches. Focusing on REXS only, noteworthy fields are: the observation of multiple order parameters, the detection of multipolar moments, but also applications in chemistry and materials sciences, macromolecules and soft matter in the soft X-ray range. REXS has evolved from the exploitation of large resonant signals to a powerful experimental and characterisation method aimed at unravelling new phenomena. The recent technical and theoretical advances have paved the way to further REXS developments in many fields of science.
