Abstract
Temperature dependent synchrotron x-ray diffraction studies of PMN-PT single crystals confirmed the existence of anti-ferroelectric fluctuations produced by correlated atomic displacements using state-of-the art experimental facilities. Detailed quantitative analysis of the corresponding superlattice reflections has been performed for the first time.
