Abstract

The heat capacity of β-pyrochlore CsTeMoO6 and CsV0.625Te1.375O6 complex oxide was investigated by adiabatic vacuum calorimetry and differential scanning calorimetry in the temperature range T = 5–500 K. The standard thermodynamic functions (heat capacity \(C_{{\text{p}}}^{ \circ }\) , enthalpy [H°(T) − H°(0)], absolute entropy [S°(T)], and Gibbs free energy [G°(T) − H°(0)] were calculated for the range from T → 0 to 500 K based on the obtained experimental data. The low-temperature (T < 50 K) heat capacity was analyzed in terms of the multifractal model, and the layered–chain structure topology of the studied compounds was established.
