  • The MagnetoCaloric Effect (MCE) is a physical property of magnetic materials consisting in a temperature variation of the sample when applying or removing a magnetic field; such temperature variation is generated by the entropy change induced on the system by the magnetic field variation. Up to now, different classes of promising materials are under investigation; among them Ni-Mn based Heusler alloys show remarkable properties. Ni2MnX (X=Ga, Sb, Sn, In) alloys are multifunctional materials which undergo a martensitic transformation between two magnetically ordered phases; the interplay between structure and magnetism is responsible for a series of unusual properties, such as magnetic shape memory, magnetic superelasticity, giant magnetocaloric effect and giant magnetoresistance.This is a very promising situation from the magneto-caloric point of view; in fact, in these samples it is realized a coupling between the martensitic transformation and the onset of magnetic ordering; large and positive entropy changes (inverse MCE) are found. (ΔS values up to 17 J/Kg K in a 5T field). (literal)
