A phenomenological model of free energy is presented to demonstrate a phase transition from a state with supersymmetry to a state without supersymmetry. The model is equivalent, in a commensurate phase, to the extended sublattice model for antiferroelectricity and ferrielectricity. In a selected set of parameters, the state with supersymmetry (antiferroelectric state) transforms to the symmetry broken state (ferrielectric state), with decreasing temperature. The transition is either first or second order one depending on the coefficients of the free energy.
