Abstract
The temperature dependence of the specific heat of the Bi0.95Sm0.05FeO3 multiferroic has been studied in the temperature range 130–780 K. The substitution of samarium ions for bismuth ions in the bismuth ferrite is found to lead to the appearance of additional specific heat component that is due to the manifestation of the Schottky effect for three-level states and multiplet structure of 4f electrons of samarium ions.
