Resonant and magnetic x-ray diffraction

Abstract

Hard X-rays magnetic scattering takes advantage of the characteristic properties of X-ray beams at third generation synchrotron radiation facilities: tuneable photon energy, controllable polarization and polarization analysis, excellent stability and brilliance. The aim of this lecture is to review the experimental and theoretical works in the domain of magnetic non-resonant and resonant X-ray diffraction on single crystals and thin films to investigate the electronic and magnetic long range order in strongly correlated electron systems. A general introduction to the theoretical aspects of the interaction between polarized photons and electrons will be given, with special emphasis to the description of the experimental polarized X-ray scattering methods to measure the relevant physical parameters.
