| Abstract: | The nature of the slow evolution of a soliton system in an incommensurate phase of a ferroelectric is investigated experimentally.
It is shown that the duration of the time interval in which the anomalous permittivity and the corresponding soliton spacings
are governed by a logarithmic law increases from a few minutes to several hours as the ferroelectric phase transition is approached.
