Webb15 nov. 2024 · The magnetic-field-induced MT produced a 3% strain under an 8 T magnetic field. More interestingly, the output stress reached as high as 100 MPa, which is much higher than Ni–Mn–Ga alloys. Figure 1.3 shows the dependence of MT temperature and Curie point on the composition of Ni 50 Mn 50−y X y (X = In, Sn, Sb) alloys.
