Summary: | The microstructure of samples of different composition belonging to the cation-deficient La1/3−xLi3xNbO3, 0≤x≤0.06, solid solution has been studied by selected area electron diffraction and high resolution transmission electron microscopy. The materials show a perovskite-related structure with basic lattice parameters a∼√2ap, b∼√2ap, c∼2ap. Besides, short-range cation ordering gives place to a larger unit cell of dimensions a∼3.5√2ap, b∼√2ap, c∼4ap. The lithium-containing compunds also present a complex microdomain structure of the octahedra tilting framework. |
