ferroelectricity

Ferroelectricity is a property of certain materials where, under normal conditions, they can have a natural electric polarization—meaning their electric charges are separated in a specific direction. This polarization can be reversed by applying an external electric field, similar to how magnets can be magnetized or demagnetized. This behavior is due to the internal structure of the material, where electric dipoles (pairs of positive and negative charges) align in a particular way. Ferroelectric materials are used in electronic devices like memory storage, capacitors, and sensors because they can retain their electric state even after the external field is removed.
