Abstract

The specific heat of the doped blue bronzes Tl0.3-xKxMoO3(x = 0.06, 0.15) has been measured in the temperature range between 100 and 220 K. Anomalies were observed at 165.7 K and 164.8 K for Tl0.24K0.06MoO3and Tl0.15K0.15MoO3, respectively. The specific heat jump, and the entropy and enthalpy changes associated with the CDW phase transition are estimated. The results suggest that the Peierls phase transition is of second order. By analogy with the behavior of pure Tl0.3-xMoO3, it shows that in the quasi-one-dimensional blue bronze, the perfect order of the interlayer alkali or thallium polyhedral chain plays an important role in the Peierls phase transition.
