Explain ferroelectricity.
Ferroelectricity:- Materials of ferroelectric have a high dielectric constant that is non-linear that is, this depends to a considerable extent on the intensity of electric field. These materials exhibit hysterisis loops that are the polarization is not a linear function of applied electric field. When the center of gravity of the positive and negative charges into a body does not coincide in absence of an applied electric field, therefore substance has an electric dipole moment. Hence material is said to be spontaneously polarized and termed as ferroelectric material. That substance is termed as ferroelectric. This contains small regions termed as ferroelectric domains and all dipoles are parallely oriented in domain although different domains are randomly oriented into the absence of an external electric field. While the temperature exceeds a particular value termed as the Curie point, the substance loses its ferroelectric properties. Examples are: Rochelle salt, Barium titanate and Potassium dihydrogen phosphate.
