Abstract

The Ni-Mn-Z (Z = Sn, In, Sb, Ga) based alloys are considered as promising magnetic refrigeration materials due to its giant inverse magnetocaloric effect, simple preparation and low cost. In this work, the transformation behavior and magnetocaloric effect of Ni ₄₂ Co ₈ Mn _37.7 In _12.3 polycrystalline alloy has been investigated. It is found that both the temperature-induced martensitic transformation and its associated field induced metamagnetic transition occur near the room temperature. The large magnetic entropy change ΔS _M of 14.30 J·K ⁻¹ ·kg ⁻¹ and large refrigeration capacity RC of 549 J·K ⁻¹ are achieved under 6 T within the broad ambient working temperature range of 248–295 K. Its magnetocaloric performance is outstanding among a great number of reported Ni-Mn-Z based alloys.
