Ferroelectrics and multiferroics

Ferroelectrics and multiferroics are a class of materials that exhibit switching of their physical properties under an external influence. Ferroelectrics demonstrate a switchable electric polarization when an electric field is applied. Multiferroics exhibit a similar ‘ferroic’ behaviour in two or more of their (usually electric, magnetic or elastic) properties.
