Exchange Bias

This timely book covers basic mechanisms, characterization, theoretical simulations, and applications for exchange bias in granular nanosystems, thin films, and bulk systems. After an overview of the field and key principles, the next section covers nanogranular (core-shell) systems, followed by chapters on thin films, bilayers/multilayers nanostructures, dilute magnetic semiconductors, and multiferroic systems. A final section turns to bulk systems, such as those consisting of perovskite structures, rare earth-transition metal intermetallic, and ion implantations. Readers of this book will obtain - A complete, modern overview on exchange bias phenomena, covering synthesis, characterization techniques, and applications - An introduction to all the important phenomenological models proposed for thin films, bulk materials, and nanoparticles - Detailed discussion of the importance of size, shape, cooling field, and temperature on exchange bias properties - Understanding of novel applications of exchange bias systems
