Figure 1

(colour online) The characteristic change of the equilibrium magnetization within a periodic driving cycle as given by the Langevin function ( , equation (10)) and Rosensweig’s chord susceptibility ( , (12)) for different amplitude magnetizing field . At low field amplitudes the two curves are identical (a). At increasing field amplitudes only the extrema remain identical.
