Electrical Properties of Ferroelectric materials

Home \ experiment
Student Manual

Ferroelectric materials are dielectric materials whose spontaneous polarization has at least a couple of equilibrium states. The macroscopic polarization of these materials is switchable by applying an external electric field. They are a special type of polar material. Not all materials having molecular dipole moment are ferroelectric materials. For instance, individual water molecules possess effective electric dipole moments, but they are randomly oriented in space and these molecular dipole moments do not spontaneously polarize so water is not a ferroelectric material.

Sample Results Ferroelectric loop at 130˚C
Another instance of a ferroelectric loop at 110˚C
Ferroelectric loop at 80˚C
Simulation results when sample capacitor is a conventional linear capacitor
