Summary:The influence of structural phase transitions, features of electronic structure, and magnetic transformation on the temperature dependence of the heat capacity of LnAO 4 (A = P, V, Nb) compounds has been considered. It has been shown that the sum of the contributions to the thermodynamic functions due to the phase transition can vary depending on the lanthanide ion. The contribution to the standard entropy caused by low-temperature phase transitions is the most significant.
