The temperature dependence of the heat capacity of nanostructured SmFeO3 ceramics obtained by mechanical activation in the temperature range of 120-800 K has been studied. It has been shown that the excess heat capacity of mechanically activated ceramics is due to: displacements of iron and samarium ions and with a change in the angle between FeO6 oxygen octahedra. Keywords: multiferroics, heat capacity, samarium ferrite, Schottky heat capacity, nanostructured ceramics, mechanical activation.
