摘要：
In this work, using a scaling data method based on the mean-field theory (MFT), magnetization isotherms M (H, T) and magnetic entropy change -Delta SM(T) curves have been simulated using MFT combined with the Bean-Rodbell model which verified the second-order phase transition for Gd3Ni2 and Gd3CoNi compounds. Under a low value of magnetic field H, M (T) and -Delta SM(T) curves have been successfully simulated and some magnetocaloric properties have been evaluated using the phenomenological model.
