Multienergy anomalous diffuse scattering

The method of multienergy anomalous diffuse scattering (MADS) developed in the Institute of Physics ASCR, v.v.i. combines the advantages of holography and diffraction improving essentially the quality of the images of local atomic structures. In contrast to holography, MADS makes possible imaging of light atoms and provides more structural information. The method of MADS was applied to the study of the local arrangements of atoms in relaxor ferroelectrics Na_1/2Bi_1/2TiO₃, PbMg_1/3Nb_2/3O₃ , PbMg_1/3Ta_2/3O₃ and to the study of local structural changes in materials during phase transitions.
