- •
The low temperature heat capacity of CaMoO4 single crystal was measured.
- •
Thermodynamic functions (entropy, enthalpy, and Gibbs free energy) were calculated.
- •
The Debye temperature at absolute zero was calculated.
- •
The characteristics of low-frequency part of the phonon spectrum were obtained.
- •
The low-frequency “bosonic” peak in the phonon density of states was discovered.
