Abstract

The experimental data on memory effects in an incommensurate phase are analyzed both in undoped layered TlInS2 crystals selected from different technological batches and in TlInS2: La. Various types of unusual memory effect are detected. It is shown that the observed memory effects are due to pinning of the soliton superstructure by a defect density wave in the internal field of the electret state.
