Optimizing the Caloric Properties of Cu-Doped Ni-Mn-Ga Alloys.

With the purpose to optimize the functional properties of Heusler alloys for their use in solid-state refrigeration, the characteristics of the martensitic and magnetic transitions undergone by NiMnGaCu ( = 3-11) alloys have been studied. The results reveal that, for a Cu content of = 5.5-7.
