Phenomenological Modeling of Magnetocaloric Effect for Ni58Fe26Ga28 Alloy

The magnetocaloric effect (MCE) of shape memory Ni58Fe26Ga28 has been investigated. A phenomenological model is used for simulation of magnetization dependence on temperature variation to investigate magnetocaloric properties such as magnetic entropy change and heat capacity change. The results indicate the potential of Ni58Fe26Ga28 alloy to achieve the MCE at temperatures near Curie temperature. This alloy presents a good-looking approach for cooling applications in its prospective candidate for a cooling system in a wide temperature interval including room temperature. The results also confirmed that the phenomenological model is useful for prediction of the MCE for magnetic materials.
