Abstract:
The heat capacity of ceramic BiFe1−xZnxO3 multiferroics has been studied in the temperature range 150–750 K. It is found that the antiferromagnetic transition temperature TN slightly shifts to lower temperatures as the concentration of the substitutional impurity Zn increases. An excess heat treatment has been observed; it is considered as the Schottky anomaly in three-level states.
