摘要	The magnetic properties and magnetocaloric effects of Ni(50-x)Mn(38+x)Sb(12) ferromagnetic shape-memory alloys with x = -1, 0, 1 and 2 that undergo a martensitic transformation were investigated. The magnetic-entropy changes Delta S of nominal Ni(49)Mn(39)Sb(12), or Ni(49.5)Mn(38.6)Sb(11.9), at 279K is 6.15 J kg(-1) K(-1) for a magnetic-field change Delta B = 1 T, with negligible hysteresis loss, as it transforms from a low-temperature martensitic phase to a high-temperature austenitic one. The large inverse Delta S in a small field change and the negligible hysteresis loss, along with the low cost of Sb, indicate that Ni(49)Mn(39)Sb(12) is a promising candidate for room-temperature magnetic refrigeration.
