Exchange Bias

This book covers basic mechanisms, characterization, theoretical simulations, and applications for exchange bias in granular nanosystems, thin films, and bulk systems. Nanogranular (core-shell) systems are discussed, followed thin films, bilayers/multilayers nanostructures, dilute magnetic semiconductors, and multiferroic systems, and bulk systems.

Surender Kumar Sharma, PhD, is Professor in the Department of Physics and Group Leader and Coordinator of the Functional Nanomaterials Laboratory at the Universidade Federal do Maranhão (UFMA) in São Luis, Brazil. Dr. Sharma has obtained his PhD degree in July 2007 from H. P. University, Shimla India. He has previously worked several years in research/academic positions in Brazil, France, Czech Republic, India, Mexico, focusing on the area of nanomagnetism and functional nanomaterials. At present he is an active member of post-graduate research program at UFMA and actively involved in research, teaching and supervising research students at UG/PG levels. He has been awarded FAPEMA Senior Researcher grants and to date has published more than fifty peer-reviewed articles and has attended numerous international conferences.
