Resumen
A brief description of the state of the artof polycrystal structure analysis by synchrotron light diffraction and
scattering is presented. Recent contributions by our group in the fields of θ-2θ powder diffraction and twodimensional
(2D) diffraction-scattering are divulged. Case studies, linked with ferroic materials, are discussed.
Extreme high brilliances of the x-rays available at synchrotrons allow researchers to use remarkably intense
and monochromatic beams and so to explore fine but important structural details of the generality of materials.
By careful analysis of θ-2θ diffraction peaks splitting, our group has characterized subtle, conflicting or nonpreviously
reported, symmetry break-downs in ferroic materials. Experiments with 2D detectors have enabled
the investigation of intensities distributions in reciprocal space along sharp diffraction peaks from textured
polycrystals as well as inside diffuse scattering zones caused by strained and/or nano-sized objects
