Investigation of the thermal hysteresis in the thermopower of (NbSe4)/10/3I

The authors report the resistivity and the thermopower (TEP) measurements of the linear chain compound (NbSe4)/10/3I which show substantial hysteresis between the cooling and the heating cycles below and above the Peierls transition. The magnitude of the observed TEP hysteresis increases if the system is cooled to lower temperatures. Cooling below 70 K has no further influence of the magnitude of the hysteresis loop. An indication of the time dependence of the TEP is also found. These effects are attributed to the interactions between the inhomogeneous charge density (CDW) superlattice and a quasi-periodic defect structure which has been found in (NbSe4)/10/3I.
