Abstract: A large deviation technique is used to calculate the microcanonical entropy function s(v,m) of the mean-field ϕ 4 -model as a function of the potential energy v and the magnetization m. As in the canonical ensemble, a continuous phase transition is found. An analytical expression is obtained for the critical energy v c (J) as a function of the coupling parameter J.
