Curie-Weiss law

(ˈkjʊərɪˈwaɪs; -ˈvaɪs)
n
(General Physics) the principle that the magnetic susceptibility of a paramagnetic substance is inversely proportional to the difference between its temperature and its Curie point

It is well known that the susceptibility ([chi]) follows the Curie-Weiss law, [chi] = C/(T - [[theta].sub.P]), in the paramagnetic region, where C is the Curie constant and [[theta].sub.P] is the CurieWeiss temperature.
All samples have a temperature called Burn temperature at which dielectric response starts complying Curie-Weiss law and the system starts the transition into paraelectric phase.
For a normal ferroelectric above the Curie temperature, the dielectric constant follows the Curie-Weiss law:
