Abstract : Starting from a temperature-independant Hamiltonian, one discusses for some models the coexistence of the van der Waals wiggles and the Maxwell-van der Waals isotherms. The main tool of this paper is provided by the temperature-dependant excitations techniques developed in an earlier paper. Some ferromagnetic models and lattice-gas models are treated along similar lines. The van der Waals wiggles and the Maxwell-van der Waals isotherms appear below the critical temperature as two solutions of a system of self-consistent equations. The choice between the two solutions is then dictated by energy considerations. (Author)
