In situ observation of the dynamic local structure in (Formula presented) has been conducted at lower temperatures by transmission electron microscopy. The observation clearly showed that around (Formula presented) dynamic fluctuation of the local (Formula presented)-tilt region in the interior of the LTO domain occurs, even at 12 K, while (Formula presented) regions nucleated along the twin boundary are rather static. The dynamic local (Formula presented) region is thought to play a crucial role in the slight suppression of (Formula presented) and in the appearance of the incommensurate magnetic structure, both of which have been reported to occur around (Formula presented).
