Monte-Carlo Calculation of the Magnetocaloric Effect in Ni-Mn-Ga Alloys
The three-dimensional model for the theoretical description of the phase transformations and the magnetocaloric effect in shape – memory Heusler Ni2+xMn1-xGa alloys (x=0.18 – 0.27) with a coupled magnetostructural phase transition by the classical Monte Carlo method is proposed. It is shown that the isothermal magnetic entropy change upon magnetic field variations from 0 to 5 T and other magnetic properties are in good agreement with the available experimental data.
