Abstract

The martensitic transformation and magnetic properties of Mn₅₀Ni_50-xSn_x melt-spun ribbons were investigated. It is shown that the increase of Sn content results in a nearly linear decrease of martensitic transformation temperatures in the ribbons, with an average rate of 70 K per at % of Sn. In Mn₅₀Ni₄₀Sn₁₀ ribbons, the field-induced reverse martensitic transformation from a weak magnetic martensite to a ferromagnetic austenite was realized due to the strong magnetostructural coupling. Under a field change of 5T, the large magnetic entropy change of 13.7 J kg^-1K^-1 and the effective refrigerant capacity of 72.9 Jkg^-1 were obtained in Mn₅₀Ni₄₀Sn₁₀ ribbons.
