A general introduction to the diffraction techniques available at SNBL will be presented by Dmitry Chernyshov (Swiss-Norvegian Beam Lines at the European Synchroton Radiatopn Facility, Grenoble, France) with a special emphasis on single crystal and thin film applications. The techniques will be illustrated with Bragg and diffuse scattering experiments done at SNBL with materials showing strong electronic, polar, and spin correlations. An incomplete list of these examples includes metal-insulator transition and spin state ordering in complex cobaltites, superconductivity and phase separation in Cs0.8Fe1.6Se2, short-range correlations in relaxor ferroelectrics, Verwey transition in magnetite, temperature and pressure evolution of molecular spin-crossover materials. An overview of future development and new opportunities for experiments will also be discussed.
