The heat capacity and thermodynamic functions of EuPO4 over the temperature range 0-1600 K
Abstract
The heat capacity of EuPO4 was measured by adiabatic calorimetry over the temperature range 9.81-298.48 K. The experimental and literature data were generalized to obtain the temperature dependence of the heat capacity of europium orthophosphate from 0 to 1600 K. This dependence was used to calculate thermodynamic functions (entropy, enthalpy, and reduced Gibbs energy). The data on the heat capacity of europium orthophosphate and diamagnetic lanthanum orthophosphate were used to estimate the noncooperative magnetic transition (Schottky anomaly) value.
