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 Ni(50-x)Mn(38+x)Sb(12) 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 Ni(49)Mn(39)Sb(12) 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 Ni(49)Mn(39)Sb(12) alloy may be a promising candidate for magnetic refrigeration above room temperature.
