Effect of Fe substitution on the magnetic, transport, thermal and magnetocaloric properties in Ni50Mn38−xFexSb12 Heusler alloys

Effect of Fe substitution on the magnetic, transport, thermal and magnetocaloric properties in Ni50Mn38−xFexSb12 Heusler alloys

The structural, magnetic, transport, thermal, and magnetothermal properties of quaternary Heusler alloys Ni50Mn38−xFexSb12 have been studied. Powder x-ray diffraction and temperature dependence of magnetization studies reveal that with the addition of Fe in the Mn site, the martensitic transition shifts to low temperatures. It is also found that the martensitic …
