Tailoring magnetic and magnetocaloric properties of martensitic transitions in ferromagnetic Heusler alloys
Abstract
Ni50Mn34In16 undergoes a martensitic transformation around 250 K and exhibits a field induced reverse martensitic transformation and substantial magnetocaloric effects. We substitute small amounts Ga for In, which are isoelectronic, to carry these technically important properties to close to room temperature by shifting the martensitic transformation temperature.
