Derivation of isothermal \({\left( \frac{\partial S}{\partial H}\right) _{T}}\) curves via the Maxwell relation. (a) \(\frac{dM}{dT}-T\) curves measured upon decreasing temperature. The data indicated by the dotted lines were not used for the Maxwell relation. (b,c) Isothermal \(\frac{dM}{dT}-H\) curves of the (b) AFM and (c) FRI phases. The solid lines represent the best-fit results (see the main text). The legend shown in (b) also applies to (c).
