Hysteresis loops in KH 2 PO 4 (KDP) and its ferroelectric (FE) isomorphs disappear some 60 K below T c . This disappearance may result from an order-disorder transition of the domain wall. The lowest energy wall consists of a single layer of nonpolar H 2 PO 4 groups of Slater energy 1 0 . Including
