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.
Ferroelectricity - Engineering LibreTexts
Ferroelectricity is a property observed in certain materials characterized by the presence of a spontaneous electric polarization without the presence of an electric field, much like how ferromagnetism is characterized by a spontaneous, permanent magnetic field.

Ferroelectricity, property of certain nonconducting crystals, or dielectrics, that exhibit spontaneous electric polarization (separation of the centre of positive and negative electric charge, making one side of the crystal positive and the opposite side negative) that can be reversed in direction.
Ferroelectricity - an overview | ScienceDirect Topics
Ferroelectricity is a subset of pyroelectricity and piezoelectricity and is defined by reversible polarization through application of an electric field. Interest in ferroelectric properties has occupied a place in modern science and technology with different electronic applications.

2020年1月27日 · Ferroelectricity was experimentally discovered one hundred years ago, spurring research on its fundamental properties and potential applications.
2.1 What is a ferroelectric? A ferroelectric material has a permanent electric dipole, and is named in analogy to a ferromagnetic material (e.g. Fe) that has a permanent magnetic dipole. One way to understand how ferroelectricity can arise is to start by looking 2. at small molecules. A molecule that is symmetric, such as methane (CH.
