Los antiferroeléctricos son materiales no polares que, bajo un campo eléctrico, cambian a una naturaleza ferroeléctrica (polar), mostrando así la característica histéresis doble de polarización-voltaje. [...]
Antiferroelectrics are non-polar materials which, under an electric field, switch to a ferroelectric (polar) nature, thus displaying the characteristic double-loop polarization-voltage hysteresis. They are currently being studied intensively, both from the fundamental point of view, to investigate what is the origin and behaviour of their functional response, and also from a practical point of view, as they are suitable for electrostatic energy storage and promising for applications in electromechanical transduction and electrocaloric cooling.
