Abstract

Accompanied by a second-order paramagnetic to ferromagnetic transition, a large reversible negative Δ S_m above room temperature has been observed in Ni_{50 - x} Mn_{38 + x} Sb₁₂ alloys besides low-field magnetic entropy change Δ S_m around/below room temperature. A - Δ S_m^max of 5.21 J kg^-1 K^-1 is acquired at 347 K in nominal Ni₄₉ Mn₃₉ Sb₁₂ alloy for a magnetic-field change from 0 to 5 T, with a refrigerant capacity of 184 J kg^-1. The large reversible Δ S_M and the high reversible refrigerant capacity indicate that Ni₄₉ Mn₃₉ Sb₁₂ alloy may be a promising candidate for magnetic refrigeration above room temperature.
