(BaNa)TiO was carried out by a synchrotron radiation X-ray pair-distribution function (PDF) method. The PDF peak is resolved as a doublet owing to the presence of two phases with distinct local structures, those are rhombohedral and tetragonal phases. The dominant rhombohedral phase is stabilized by the Li substitution. The depolarization temperature () is increased as increasing the rhombohedral component in the local structure.
