DOI: 10.1063/1.5041954
Abstract: 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… read more here.
