Multiferroic Materials: Properties, Interactions, and the Physics Behind

Reflecting the recent surge of interest in this topic, this book is essentially devoted to the fundamental physics underlying multiferroic materials. Written by experts on optical spectroscopy, the text enables readers to gain an insight into the complicated interplay of the individual effects, and to understand the behavior of materials for technical applications in microelectronics and spintronics. It focuses on the magnetic and electric properties of multiferroics and the microscopic mechanisms involved, covering the physical properties and the new physics that arises from their mutual coupling. The authors address possible mechanisms at the origin of such couplings and discuss the couplings between magnetic and ferroelectrics properties in terms of thermodynamical and spectroscopical measurements from an experimental point of view. For academic researchers involved in condensed matter physics as well as materials sciences and engineering, as well as graduate students wishing to carry out research in material and condensed matter sciences.
