Popis: The generalized statistical dynamical theory of X-ray diffraction by imperfect single crystals is applied for the structural characterization of real single crystals with complex basis, namely, gadolinium gallium garnet (GGG) crystal Gd3Ga5O12. The developed theoretical approach takes into account the presence of various structural defects as well as provides the self-consistent description of coherent and diffuse components of diffraction profiles from such crystals. The characteristics of microdefects in the investigated GGG single crystal have been determined by analyzing the rocking curves measured for 444 and 888 reflections of CuKα1 radiation.
