摘要	Accompanied by a second-order paramagnetic to ferromagnetic transition, a large reversible negative Delta S-m above room temperature has been observed in Ni50-xMn38+xSb12 alloys besides low-field magnetic entropy change Delta S-m around/below room temperature. A -Delta S-m(max) of 5.21 J kg(-1) K-1 is acquired at 347 K in nominal Ni49Mn39Sb12 alloy for a magnetic-field change from 0 to 5 T, with a refrigerant capacity of 184 J kg(-1). The large reversible Delta S-M and the high reversible refrigerant capacity indicate that Ni49Mn39Sb12 alloy may be a promising candidate for magnetic refrigeration above room temperature.
