Resumen

Magnetic and conventional shape memory properties of Mn₄₉Ni₄₂Sn₉(at.%) and Mn₄₉Ni₃₉Sn₉Fe₃(at.%) polycrystalline alloys exhibiting martensitic transformation from ferromagnetic austenite into weakly magnetic martensite are characterized under compressive stress and magnetic field. Magnetization difference between transforming phases drastically increases, while transformation temperature decreases with the addition of Fe. Both Mn₄₉Ni₄₂Sn₉ and Mn₄₉Ni₃₉Sn₉Fe₃ alloys show remarkable superelastic and shape memory properties with recoverable strain of 4% and 3.5% under compression at room temperature, respectively. These characteristics can be counted as extraordinary among the polycrystalline NiMn-based magnetic shape memory alloys. Critical stress for phase transformation was increased by 34 MPa in Mn₄₉Ni₃₉Sn₉Fe₃ and 21 MPa in Mn₄₉Ni₄₂Sn₉ at 9 T, which can be qualitatively understood in terms of thermodynamic Clausius-Clapeyron relationships and in the framework of the suggested physical concept of a volume magnetostress.
