Abstract
A study of the magnetocaloric effect (MCE) in the ferromagnetic Heusler alloys Ni50 Mn37+x Sb13-x (x=0,0.5,1) has been carried out through magnetization measurements. An inverse magnetocaloric effect was observed in the vicinity of the first order martensitic transition. A maximum positive magnetic entropy change of Δ Sm ≈19 Jkg K at approximately 297 K for a magnetic field change of 5 T was observed. It is demonstrated that the martensitic transformation temperature, and the corresponding Δ Sm, can be tuned through a slight variation in composition. © 2007 American Institute of Physics.
