Thermodynamic characteristics of cobaltite(nickelite)-cuprate-manganites LaSrCoCuMnO6 and LaSrNiCuMnO6
Annotation
The temperature dependences of the specific heat of nanoscale (nanocluster) cobaltite(nickelite)-cuprate-manganites LaSrCoCuMnO6 and LaSrNiCuMnO6 have been studied via experimental dynamic calorimetry in the range of 298.15673 K. The temperature dependences of the specific heat Cpf(T) of LaSrCoCuMnO6(at 323 and 523 K) and LaSrNiCuMnO6(at 348 K) exhibit anomalous jumps in the specific heat, which are likely due to the second-order phase transitions. Based on the experimental data on C(T) and the calculated value of entropy S(298.15), the temperature dependences of the specific heat and thermodynamic functions of the studied compounds are calculated in the temperature range of 298.15673 K.
