Mn. Palatnikov et al., DIELECTRIC BEHAVIOR AND ORDERING OF FERROELECTRIC SOLID-SOLUTIONS BASED ON SODIUM NIOBATE, Inorganic materials, 33(9), 1997, pp. 963-969
The dielectric properties and nonlinear dielectric and optical behavio
r of LixNa1-xTayNb1-yO3 solid solutions were studied over a wide tempe
rature range. We present experimental evidence that cation ordering in
the alkali-metal site occurs at an Na : Li ratio of 7 : 1.
