A transition from a ferroelectric to either another ferroelectric, or a paraelectric, or an antiferroelectric state. Example: The transition of the low-temperature, cubic paraelectric BaTiO3 to the high-temperature, tetragonal, ferroelectric form at .
Notes:
- In an antiferroelectric transition individual dipoles become arranged antiparallel to adjacent dipoles with the result that the net spontaneous polarizationis zero.
- Ferroelectric/antiferroelectric transitions also occur in the liquid-crystal state. These states are dependent on the alternating nature of dipoles between layers in thesmectic state.
