Magnetization functions M(T) (a), and their temperature derivatives dM(T)/dT (b), computed using Eq. (8) for ferromagnets undergoing SPTs at 120 K (solid lines) and 140 K (dashed lines), TC = 110 K. The values computed for the ferromagnet, which does not undergo structural phase transition, are shown by the dash-dotted lines. Inset: Temperature dependence of magnetization of Ni53.1Mn26.6Ga20.3 alloy, measured (circles) and computed using Eq. (8) (line).
