Abstract

The dielectric response in the incommensurate (IC) phase of (PbySn1–y)2P2Se6 solid solutions shows a low-frequency dielectric dispersion (50 Hz–100 kHz) with a sharp decrease in ε at low temperatures (T<50 K). This dispersion is due to a relaxation of the IC modulation, pinned by the substituting Pb atoms that can be considered as defects, through a series of metastable states. The dispersion has a Debye-like polydispersive character, with an additional low-frequency logarithmic correction related to the frequency dependence of the length scale on which the pinned incommensurations relax.
