dc.description.abstractThis study modeled and investigated the magnetocaloric effect in Ni2MnGa Heusler alloy characterized by its magnetic entropy change (Delta S-m) and its refrigerant capacity (RCFWHM) by using the effective field theory. It was found that the peak of the negative magnetic entropy change (Delta S-m(pk)) and the RCFWHM decreased as the external magnetic field increased, whereas the full width half maximum peak (delta T-FWHM) and the temperature (T-pk) of the Delta S-m(pk) both increased. At higher external magnetic fields, delta T-FWHM and T-pk were close to each other, but the Delta S-m(pk) and RCFWHM were separated from each other. The RCFWHM of the corner atoms (Ni1 and Ni3) was higher than those of the central atom (Ni5). This result revealed that corner atoms have an important role in the magnetocaloric properties of Ni2MnGa and other materials with a magnetocaloric effect.
