Abstract

We introduced different amounts of Li⁺ ions into La_1/3NbO₃ with an A-site-deficient perovskite structure and determined crystal structures of the resultant oxides La_1/3Li_xNbO₃ (x = 0, 0.075, and 0.444). Reflections arising from superstructures appeared in their neutron powder diffraction patterns. Rietveld refinements revealed that the superstructures result from tilting of NbO₆ octahedra and ordering of cations and vacancies at A sites. La_1/3Li_xNbO₃ varied from an insulator to a semiconductor with increasing x.
