Heat capacity and thermodynamic functions of LaVO4 and LuVO4 from 7 to 345 K

The heat capacities of lanthanum and lutetium orthovanadates have been measured at temperatures from 7 to 345 K using an adiabatic calorimeter. No anomalies have been detected in the heat capacity data. The thermodynamic functions ( C p 0 ( T ), S 0 ( T ), and H 0 ( T ) − H 0 (0)) of the two compoun...

More Information
Summary:The heat capacities of lanthanum and lutetium orthovanadates have been measured at temperatures from 7 to 345 K using an adiabatic calorimeter. No anomalies have been detected in the heat capacity data. The thermodynamic functions ( C p 0 ( T ), S 0 ( T ), and H 0 ( T ) − H 0 (0)) of the two compounds have been calculated in the temperature range studied, and their Debye characteristic temperatures have been estimated.
