Abstract. We prove that in three or higher dimensions, an isotropic,
ferromagnetic, nearest-neighbor O(N) perturbation of a nematic liquid crystal
model (also having isotropic, nearest-neighbor
interactions) has an intermediate phase. In this intermediate phase,
the liquid crystal order parameter is non-zero but the spontaneous
magnetization is zero while at low temperatures, these systems exhibit
magnetization.
