ABSTRACT
The structure and diffuse scattering in uniaxial relaxor Sr0.6Ba0.4Nb2O6 single crystal have been studied by x-ray diffraction at room temperature. Two different kinds of local ordering with different correlation lengths and different shapes of correlation functions have been revealed. The values of correlation lengths have been determined from analysis of experimental data. These types of orderings are connected with the intrinsic structure of crystal and can promote the appearance of relaxor properties.
