Realization of Magnetostructural Transition and Magnetocaloric Properties of Ni–Mn–Mo–Sn Heusler Alloys

As magnetic cooling refrigerant, Ni–Mn–Sn Heusler alloys have gained significant potentials for a wide range of practical applications as compared with other expensive Ga-doped Ni–Mn based Heusler alloys, toxic As and P doped Mn-based alloys and rare-earth elements like Gd-based alloys. Consequently...

Description
Summary:As magnetic cooling refrigerant, Ni–Mn–Sn Heusler alloys have gained significant potentials for a wide range of practical applications as compared with other expensive Ga-doped Ni–Mn based Heusler alloys, toxic As and P doped Mn-based alloys and rare-earth elements like Gd-based alloys. Consequently, an inclusive investigation on magnetostructural transition and magnetocaloric features of Ni 43 Mn 47− x Mo x Sn 10 alloys is carried out. The alloys are assembled through arc-melting technique and their X-ray diffraction analysis confirms their B 2 -type crystal structure at room temperature. As the Mo contents are increased, the magnetostructural transition temperature increases for a temperature range between Curie temperature of austenite and martensite phases. Obvious metamagnetic behavior and magnetic hysteresis are observed in isothermal magnetization curves, suggesting that the temperature and magnetic field can be used as robust tools for tuning the structural transformation in Heusler alloys. The noticeable magnetocaloric effect suggests that the prepared alloys can be an attractive choice for magnetic refrigeration applications.
