Abstract

The heat capacity of ceramic BiFe_1–xZn_xO₃ multiferroics has been studied in the temperature range 150–750 K. It is found that the antiferromagnetic transition temperature T_N 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.
