Abstract
A two-component smectic undergoing a demixing tran~ition to two coexisting smectic pha~es exhibits a novel spinodal pattern as observed by light ~cattering and optical microscopy. We show that this ~pinodal, characterized by a prescribed angle between the mo~t intense wavevectors and the layer normal, is the result of the instability of the baroclinic mode of two-cojnponent smectic hydrodynamics.Keywords
