A transition from a ferroelectric to either another ferroelectric, or a paraelectric,
or an antiferroelectric state. Example: The transition of the low-temperature, cubic
to the high-temperature, tetragonal, ferroelectric form at
In an antiferroelectric transition individual dipoles become arranged antiparallel
to adjacent dipoles with the result that the net spontaneous polarization is zero.
Ferroelectric/antiferroelectric transitions also occur in the liquid-crystal state. These states are dependent on the alternating nature of dipoles between layers in
the smectic state.
