Heat capacity and thermodynamic functions of Gd(VO4 )0.5 (PO4 )0.5 solid solution in the low-temperature region
A series of Gd(VO4)1−x (PO4) x solid solutions with a xenotime structure was synthesized. The heat capacity of a Gd(VO4)0.5(PO4)0.5 solid solution sample was measured by adiabatic calorimetry in the low-temperature region (6–348 K). The thermodynamic functions were calculated within the studied temperature range.
