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. All ferroelectrics are pyroelectric, with the additional property that their natural electrical polarization is reversible.

What is ferroelectricity in chemistry?

Ferroelectricity is a property of certain materials to have a spontaneous polarization which can be reversed by the application of an external electric field. From: Progress in Solid State Chemistry, 2015.

What does ferromagnetism and ferroelectricity mean?

Let us start with the basic definition; a ferroelectric is defined to be a material with a spontaneous electric polarization that is switchable by an applied electric field. Likewise, a ferromagnet has a spontaneous mag- netization that can be reoriented by an external magnetic field.
