Thermal hysteresis in the low frequency dielectric response of charge density wave systems TaS3 and K0.3MoO3
The low frequency dielectric response of charge density wave systems K0.3MoO3 and o-TaS3 shows a hysteresis on temperature cycling. In both systems the closing of the hysteresis at low temperature coincides with the closing of the hysteresis in the DC conductivity and corresponds to the temperature of the glass transition observed in the dielectric response of these two systems. The AC conductivity is higher on heating, while the DC conductivity is lower, i.e. two loops have opposite directions. The higher AC conductivity (or dielectric response) is a consequence of a more corrugated CDW phase on heating.
