Diffuse scattering occurring in the Bragg diffraction pattern of a long-range-ordered structure represents local deviation from the governing regular lattice. However, interpreting the real-space structure from the diffraction pattern presents a sign

The ability of the pair distribution function analysis of total scattering from a powder to determine the local ordering in ferroelectric PZN (PbZn1/3Nb2/3O3) is explored by comparing it with a model established using single-crystal diffuse scatterin
