Query: Heat capacity and magnetocaloric effect in polycrystalline
  Gd1-xSmxMn2Si2   We report the magnetocaloric effect in terms of isothermal magnetic entropy
change as well as adiabatic temperature change, calculated using the heat
capacity data. Using the zero field heat capacity data, the magnetic
contribution to the heat capacity has been estimated. The variations in the
magnetocaloric behavior have been explained on the basis of the magnetic
structure of these compounds. The refrigerant capacities have also been
calculated for these compounds.
