Ferroelectricity - Wikipedia
In physics and materials science, ferroelectricity is a characteristic of certain materials that have a spontaneous electric polarization that can be reversed by the application of an external electric field. [1][2] All ferroelectrics are also piezoelectric and pyroelectric, with the additional property that their natural electrical polarization...

电滞回线(ferroelectric hysteresis loop)是铁 电畴 在外 电场 作用下运动的宏观描述。铁电体的极化随着电场的变化而变化，极化强度与外加电场之间呈非线性关系。
Ferroelectric Materials: What Are They? (With Examples)
2012年2月24日 · Ferroelectric Definition: Ferroelectric materials are substances that can maintain and reverse their electric polarization with an external electric field. Polarization Properties: These materials exhibit a spontaneous polarization that remains even without an external field, and can be reversed by applying an opposite field.
Ferroelectricity - an overview | ScienceDirect Topics
Ferroelectricity is a property of certain materials to have a spontaneous polarization which can be reversed by the application of an external electric field. Ferroelectricity was discovered in 1920 in Rochelle Salts by J. Valasek [68]. The term is used by analogy to ferromagnetism in which a material exhibits a permanent magnetic moment.
