Figure 6
(a) M(H) curves measured during the first (open symbols) and second (solid symbols) cycles of increasing and decreasing field at different temperatures for the Ni_43.7Cu_1.5Co_5.1Mn_36.7In₁₃ microwire. The determination of the critical field (μ₀H_cr) for the magnetic field-induced phase transition is illustrated in the figure. (b) The temperature dependence of the critical field (μ₀H_cr) extracted from the second cycle of M(H) curves in panel (a). The dashed line is the linear fit line of the data (shown as symbols).
