> Ferroelectric systems have received great attention for more than 50 years because of their interesting properties, which led to the development of many applications associated to their strong coupling effects, strong hysteresis in the field polarization response, extremely high dielectric permittivity, etc. These materials have been used in ferroelectric memories, pyroelectric sensors, electromechanical transducers, medical diagnostic devices, ultrasonic motors, electro-optical devices, and in many other applications.

> Many theoretical and experimental researches have been carried out on single crystals, ce‐ ramics, thin films, ferroelectric liquids, composites, and also the ferroelectricity at nanoscale, in order to develop new technologies and also to understand the exhibited phenomena.

> The purpose of this book is to offer the results of several researches on ferroelectricity, cov‐ ering a wide range of topics on ceramics, polymers, thin films, ferroelectric liquids, compo‐ sites, ferroelectricity at nanoscale, and also on multiferroic systems. The book has been the result of an important number of contributions of researchers from the international scientif‐ ic community.

> I would like to thank all the authors for their interesting contributions to this book and the InTech team for the outstanding support.

We hope that this book be interesting for students and researchers.
