This overview is a brief introduction to the subjects covered by this book, nanomagnetism and spintronics. The discovery of giant magnetoresistance (GMR) effect is described together with a short summary of the studies prior to the experiments on GMR. Studies on various kinds of magnetoresistance (MR) effect that were inspired by the GMR effect are reviewed and recent topics are introduced. In many novel phenomena involving the interplay of electric conductance and magnetization, the role of the “spin current” has been revealed to be important and the possibility for exploiting these phenomena in spintronics devices has been suggested. Nanoscale devices are indispensable to fundamental studies on spintronics and also to various technical devices, and therefore gaining an understanding of nanomagnetism is a crucial current issue. At the end of this section, the scope of this book is described in brief with the content of each chapter.
Nanomagnetism and Spintronics
Nanomagnetism and spintronics are two close subfields of nanoscience, explaining the effect of substantial magnetic properties of matter when the materials fabrication is realized at a comparable length size. Nanomagnetism deals with the magnetic phenomena specific to the structures having dimensions in the submicron range. The fact that the electronic transport properties of materials are dependent on the magnetic properties' artificial nanostructures, i.e., giant magnetoresistance (GMR) or tunneling magnetoresistance (TMR), has revolutionized spintronics science and technology. This book explains the concepts of nanomagnetism and spintronics by viewing the most recent research works from internationally distinguished research groups. Placing special emphasis on crucial fundamental and technical aspects of nanomagnetism and spintronics, it serves as a one-stop reference for universities offering postgraduate programs in nanotechnology or related disciplines. This unique book deals with all three stages required for conducting research in nanomagnetism and spintronics including fabrication, characterization and applications of nanomagnetic and spintronics materials, providing general concepts and an insightful overview of this subject for research students and scientists from different backgrounds investigating the multidisciplinary area of nanotechnology.
