(a) The martensitic transformation behavior of Ni₅₀Mn₃₈Ga₁₀Sb₂ measured with DSC at a cooling/heating rate 20 K/min. (b) Composition-temperature phase diagram of Ni₅₀Mn₃₈Ga_12-x Sb_x (x = 0–6) alloys. (c) Simplified schematic diagrams of the domain evolution embedded in an AFM single domain and hysteresis loops at different temperature.
