  • Abstract
    The dependence of the speckle-field in Ba2NaNb5 O15 crystals in laser beam on the orientation of the crystals, temperature and direction of growing was investigated. The different pattern of scattering along the a and c axis make it possible to unambiguously determine the direction of the ferroelectric axis in the crystal, while abrupt change in the nature of scattering with a ferroelectric phase transition makes it possible to determine the Curie point
