abstract = "Procedure of determination of magnetic part of the specific heat of ferromagnetic (FM) solid from the results of the low-temperature measurements is proposed and applied to the number of non-stoichiometric Ni50Mn50-xInx alloys. It is shown that the disregard of magnetic contribution to the specific heat of FM solid results in the noticeable underestimation of Debye temperature and overestimation of the specific heat of electron subsystem of FM solid. The magnetic contribution to the low-temperature specific heat of antiferromagnetic (AFM) solid is negligibly small if N{\'e}el temperature exceeds the Debye temperature. In the opposite case the magnetic part of the specific heat of AFM solid may be comparable in value with non-magnetic part, but separation of these parts is an open problem.",
