The ferroelectric material has an electric dipole moment and it is spontaneously polarized. They have high dielectric constant which is nonlinear because it is dependent on the intensity of electric field. They also exhibit hysteresis loop. When the temperature increases above curie point, the ferroelectric material loses their ferroelectric properties.

Materials: Rochelle salt, Barium Titanate. 

Application: It is used in condensers to concentrate considerable quantities of electric energy within a small space.
