On the New Eight-Pseudospin Model for Hydrogen-Bonded KH2PO4 Family

The new eight pseudo-spin model recently introduced to discuss in a unified fashion the ferroelectric and antiferroelectric phase transitions in the hydrogen-bonded crystals of the KH 2 PO 4 family is reviewed. The dielectric susceptibilities along the unique ferroelectric c-axis, and the a (b)-axis...

Summary:The new eight pseudo-spin model recently introduced to discuss in a unified fashion the ferroelectric and antiferroelectric phase transitions in the hydrogen-bonded crystals of the KH 2 PO 4 family is reviewed. The dielectric susceptibilities along the unique ferroelectric c-axis, and the a (b)-axis, perpendicular to the unique axis, are calculated. The application to the mixed crystals is suggested.
