Аннотация
Isobaric heat capacity of magnesium-praseodymium hexaaluminate PrMgAl11O19 with magnetoplumbite structure was measured by three calorimetric methods in the temperature range 2–1865 K. Heat capacity values were docked and smoothed to calculate thermodynamic functions (entropy, enthalpy change and derived Gibbs energy) in the mentioned temperature region. A gentle anomaly of heat capacity with a maximum of about 8 K was found, its entropy and enthalpy were calculated. Magnetic properties of PrMgAl11O19 have been studied using the method of dynamic magnetic susceptibility in the temperature range 2–300 K. Based on the results of measurements of magnetic properties, an anomaly was found on the imaginary component of dynamic magnetic susceptibility, the temperature range of which is consistent with the area of the anomaly of heat capacity.
