Description
The interaction between the protons on the nearby hydrogen bonds in NH4H2PO4 (ADP)-type crystals, called the Ishibashi interaction, was analyzed to derive theoretically, i.e., not in an ad hoc way, the effective dipole-dipole interaction between PO4 radicals, which plays a substantial role in phase transitions. It turns out that at low temperatures the ADP-type antiferroelectric phase is stabilized if the Ishibashi interaction is repulsive, while the monoclinic ferroelectric phase is stabilized otherwise.
