Description

Dielectric constant and differential scanning calorimetry measurements have shown a transition to a new phase in both KOH (at 233 K) and KOD (at 257 K); the shape of the dielectric anomaly suggests electrical ordering at low temperature. Structural parameters obtained from high resolution neutron powder diffraction data demonstrate the ordering to be antiferroelectric. A preliminary account is given of the structures at 293 K and 77 K. (author)
