Electroclinic measurements are reported for a liquid crystal around the antiferroelectric smectic-[ital C][sub [ital A]][sup *-] disordered'' smectic-[ital A] phase transition. It was found that the spatially averaged tilt susceptibility exhibits a slope discontinuity at the transition, and that the extrapolated divergence temperature of the susceptibility is only 1.1[plus minus]0.1 [degree]C below the Neel temperature. The relaxation times were found to be of the order of 1 [mu]s. A simple mean-field model is presented.
