Abstract

It is shown that the transition in KDP type crystals can be described as one which possesses the dual characteristics of both ferro- and antiferroelectric properties, depending on the direction of observation. The transverse susceptibility is calculated based on a well known model for KDP, and compared with experiment. The results are in excellent agreement with the data and provide further evidence that the numerical value for the tunnelling integral is much larger in KH2PO4 than in KH2ASO4.
