Properties of Ferroelectric Materials | Electrical Engineering

The ferroelectric materials possess the following typical properties: i. They lack centre of symmetry, i.e., non centrosymmetric. ii. Their static dielectric constant changes with temperature according to the relation ԑ= C/T – Tc (Provided T > Tc) Where C is a constant independent of temperature. This relation is known as the Curie-Weiss law. C and T are the parameters of [...]
