Volume is indexed by Thomson Reuters BCI (WoS). Multiferroics: that is, materials which simultaneously exhibit both ferromagnetism and ferroelectricity - and also often ferroelasticity - now attract considerable attention because of the interesting physics involved and their promise for important practical applications. Typical multiferroics belong to the perovskite group of transition metal oxides, and include rare-earth manganites and ferrites. Several new multiferroic systems have been developed, during recent years, which exhibit very strong coupling between the ferroelectric and magnetic degrees of freedom. The present volume comprises both review articles, and research papers on various themes; with very little overlap. The authors of the review papers have generally kept in mind the unfamiliarity, of the field of ‘Ferroics and Multiferroics’, to newcomers. They cover the historical development of the field, and add their own contributions.

Magnetic, Ferroelectric, and Multiferroic Metal Oxides covers the fundamental and theoretical aspects of ferroics and magnetoelectrics, their properties, and important technological applications, serving as the most comprehensive, up-to-date reference on the subject. Organized in four parts, Dr. Biljana Stojanovic leads expert contributors in providing the context to understand the material (Part I: Introduction), the theoretical and practical aspects of ferroelectrics (Part II: Ferroelectrics: From Theory, Structure and Preparation to Application), magnetic metal oxides (Part III: Magnetic Oxides: Ferromagnetics, Antiferromagnetics and Ferrimagnetics), multiferroics (Part IV: Multiferroic Metal Oxides) and future directions in research and application (Part V: Future of Metal Oxide Ferroics and Multiferroics). As ferroelectric materials are used to make capacitors with high dielectric constant, transducers, and actuators, and in sensors, reed heads, and memories based on giant magnetoresistive effects, this book will provide an ideal source for the most updated information. Addresses ferroelectrics, ferromagnetics and multiferroelectrics, providing a one-stop reference for researchers Provides fundamental theory and relevant, important technological applications Highlights their use in capacitors with high dielectric constant, transducers, and actuators, and in sensors, reed heads, and memories based on giant magnetoresistive effects

"a very detailed book on multiferroics that will be useful for PhD students and researchers interested in this emerging field of materials science" —Dr. Wilfrid Prellier, Research Director, CNRS, Caen, France Multiferroics has emerged as one of the hottest topics in solid state physics in this millennium. The coexistence of multiple ferroic/antiferroic properties makes them useful both for fundamental studies and practical applications such as revolutionary new memory technologies and next-generation spintronics devices. This book provides an historical introduction to the field, followed by a summary of recent progress in single-phase multiferroics (type-I and type-II), multiferroic composites (bulk and nano composites), and emerging areas such as domain walls and vortices. Each chapter addresses potential technological implications. There is also a section dedicated to theoretical approaches, both phenomenological and first-principles calculations.

The magnetoelectric properties of multiferroic materials have a high potential for applications in the fields of data storage, spin valves, spintronics, memories, sensors and microelectronic devices. The book presents both a detailed literature review of the field, and the experimental results obtained from various characterization and analytical techniques performed on four series of lanthanum orthoferrite type multiferroics. These materials have been used in solid oxide fuel cells (SOFC), magneto-hydrodynamic power generation (MHD), capacitors and energy storage devices in microelectronics, non-volatile magnetic memory devices and ferroelectric random access memories (Fe-RAM). Keywords: Multiferroics, Lanthanum Orthoferrites, Ferromagnetism, Ferroelectricity, Electrical Conductivity, Thermal Stability, Dielectric Constant, Solid Oxide Fuel Cell (SOFC), Magneto-Hydrodynamic Power Generation (MHD), Capacitors, Energy Storage Devices, Magnetic Memory Devices, Ferroelectric Random Access Memories (Fe-RAM), Charge Density Measurements..

Today’s wireless communications and information systems are heavily based on microwave technology. Current trends indicate that in the future along with - crowaves, the millimeter wave and Terahertz technologies will be used to meet the growing bandwidth and overall performance requirements. Moreover, motivated by the needs of the society, new industry sectors are gaining ground; such as wi- less sensor networks, safety and security systems, automotive, medical, envir- mental/food monitoring, radio tags etc. Furthermore, the progress and the pr- lems in the modern society indicate that in the future these systems have to be more user/consumer friendly, i. e. adaptable, reconfigurable and cost effective. The mobile phone is a typical example which today is much more than just a phone; it includes a range of new functionalities such as Internet, GPS, TV, etc. To handle, in a cost effective way, all available and new future standards, the growing n- ber of the channels and bandwidth both the mobile handsets and the associated systems have to be agile (adaptable/reconfigurable). The complex societal needs have initiated considerable activities in the field of cognitive and software defined radios and triggered extensive research in adequate components and technology platforms. To meet the stringent requirements of these systems, especially in ag- ity and cost, new components with enhanced performances and new functionalities are needed. In this sense the components based on ferroelectrics have greater - tential and already are gaining ground.
