摘要：
A dielectric anomaly related to the observed departure from the Curie–Weiss law in several Aferroelectric materials has been characterized in this work in ferroelectric BaTiO3. The electrical properties of the material were investigated using the a.c. analysis technique. From the analysis of the permittivity versus frequency curves collected at various temperatures, we discuss the anomalous behaviour as a result of a low frequency dispersion phenomenon due to the characteristics of the conduction processes at the material inhomogeneities.
