摘要：

First order structural transformation (FOST) and inverse magnetocaloric effect (IMCE) were investigated in melt-spun ribbons of Ni(49)Mn(37.4)Sn(13.6) and Ni(50)Mn(34.5)Sn(15.5) Heusler alloys. Thermal and magnetic characterization of the ribbons revealed the existence of FOST. Interestingly, in the Ni(49)Mn(37.4)Sn(13.6) ribbon, the structural transformation occurs prior to magnetic transition incongruous to that observed in the Ni(50)Mn(34.5)Sn(15.5) ribbons. In addition to FOST, the ribbons also exhibit a large IMCE at low magnetic field. A maximum positive magnetic entropy change Delta S(M) similar to 6.0 Jkg(-1) K(-1) and similar to 1.6 J kg(-1) K(-1) for a field change of 2 T was observed in the Ni(49)Mn(37.4)Sn(13.6) and Ni(50)Mn(34.5)Sn(15.5) ribbons, respectively.
