    Modulated Phases and Domain Structure in Double Niobates with Tetragonal Tungsten Bronze — Like Structure

    The domain structure and the commensurate — incommensurate transition of some niobates, with general formula A2BNb5O15 where A = Ba, Sr or Pb and B = Na or K, are examined by using electron microscopy and electro...

    Incommensurate — Commensurate Phase Transition of Cu2-×Te. (x < 0.05)

    In the temperature range 25ºC to 600°C, Cu2-×Te (x<0.05) undergoes a sequence of phase transformations schematically shown in Fig. 1.1 The highest temperature phase (∊-phase) and the one stable at room tempera...

    Studying Cu2–xSe phase transformation through DSC examination

    The thermal effect accompanying the transition of Cu2–xSe into a superionic conduction state was studied by non-isothermal measurements, at different heating and cooling rates (β=1, 2.5, 5, 10 and 20°C min–1). Du...

    Dispersion of electro-optic coefficients in sillenite crystals

    The photorefractive crystals of the sillenite family (Bi12SiO20 or BSO, Bi12GeO20 or BGO, and Bi12TiO20 or BTO) that belong to the cubic 23 point group are optically active, and exhibit the piezoelectric, elasto-...
