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 AS of nominal Ni_(49)Mn_(39)Sb_(12), or Ni_(49.5)Mn_(38.6)Sb_(11.9), at 279 K is 6.15 J kg~(-1) K~(-1) for a magnetic-field change ΔB = l T, with negligible hysteresis loss, as it transforms from a low-temperature martensitic phase to a high-temperature austenitic one. The large inverse AS 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.
