As-solidified Ni48Co2Mn35In15 ribbons were prepared through the melt-spinning method, and their structural, magnetic, magnetocaloric properties, and martensitic transformations were investigated. The inverse martensitic transformation temperature (TA=325 K) for the melt spun ribbons shifted by 55 K to higher temperature relative to that of the bulk material (TA = 270 K). The working temperature range of the magnetic entropy change (ΔSM) in Ni48Co2Mn35In15 ribbons has been significantly expanded relative to that of bulk. The roles of the magnetostructural transitions on the magneto-responsive properties of the ribbons are discussed.
