Abstract:
Relatively large size single crystals of Li x Na 1- x NbO 3 were grown by Czochralski method. Three compositions of x =0.09, 0.12 and 0.16 have been studied by X-ray diffraction, dielectric measurement and ferroelectric hysteresis loops. At room temperature, the point group of crystal of x =0.09 is mm2 and that for x =0.12 and 0.16 is 4 mm. From the temperature dependence of the dielectric constant and the hysteresis loops, the transition temperature T c , Curie-Weiss temperature T o , curie-Weiss constant C , spontaneous polarization P s , coercive field E c and the high field loss tangent tan δ H were determined for each composition. The significant difference between T c and T 0 indicates the first order character of the ferro-paraelectric phase transitions. Crystals with x =0.12 shows the largest P s and the lowest E c which is ascribed to the morphotropic phase transition near room temperature for this composition.
