Abstract: We report a clear cut evidence of a temperature dependent diffusive central mode associated with the ferroelectric phase transition of LiTaO3; a detailed linshape analysis shows that this central mode is a Debye-like relaxation. We also show its influence in the dielectric constant through polariton measurements for several temperatures. © 1976.
