    • -, namely, at the boundary H/T T→0 ΔS∼0. The Clausius-Clapeyron relation established at a first-order transition is ΔS+ (dH/dT ) PG /ΔM=0, where M is the uniform magnetization. However, a generalized Ehrenfest relation can be derived along the transition line: ( dΔS dT ) PG + ( dH dT ) PG ( dΔM dT ) PG + ( d2 H d T2 ) PG ΔM=0. If the transition is of the second order (S=0 ), then all three terms vanish separately. See, e.g., 10.1016/S0921-4534(97)01811-X. Hence the vertical slope in the T→0 limit in Fig. is consistent with the second order.
