Large change of magnetic moment in Ni13Co3Mn13Sn3 and Ni13Co3Mn13Sn2Al1 Heusler alloys at martensitic transitions: Investigation from first principles

As is known, Co-doped Ni-Mn-Z (Z = Ga, In, Sn) Heusler alloys exhibit unique multifunctional properties such as the magnetic shape memory effect, magnetic-field-induced strains, exchange bias effect, giant magnetoresistance and the magnetocaloric effect (MCE), which are promising for future technologies [1-3].
