An experimental study was made of the transparency of the smectic phase of p-type n-octylhydroxybenzoic acid as a function of the intensity and frequency of an electric field. A significant thermal hysteresis was found: at a given temperature, the smectic phase obtained by heating from the solid crystalline state is less sensitive to the electric field than the phase produced by cooling from the isotropic liquid. The transparency changes are explained on the basis of the appearance, growth, and destruction of domain structure in the electric field.
