    Abstract

    We report a direct observation of the superlattice diffraction peaks, indicating a doubling of unit cell, from lead magnesium niobate (PMN) single crystal using X-ray diffraction technique. The broad width of the superlattice diffraction peaks indicates that the superlattice ordering in PMN is of short range. In the temperature range studied (from 10 K to 355 K) the peak width shows no temperature dependence. The intensity distribution among the observed superlattice peaks suggests that the doubling of unit cell in the superlattice regions involves significant ionic displacements in addition to a chemical ordering.
