Аннотация:The features of the technique of resonant synchrotron-radiation (SR) diffraction are considered.
The energy, angular, polarization, and temperature dependences of Bragg reflections at incident radiation energies that are close to the absorption edges of material atoms are studied using this technique. These dependences contain information about the electronic, magnetic, and structural features of the objects under study. The contribution of several scattering channels to the formation of the diffraction spectrum leads to the appearance of interference effects making it possible to obtain information about the scattered radiation phase. Results of some studies of resonant SR diffraction performed at the Kurchatov SR source are presented.
