Handbook Of Nanomagnetism

This unique handbook compiles and details cutting-edge research in nanomagnetism and its applications in spintronics, magnetoplasmonics, and nonlinear magneto-optics. Fundamental aspects of magnetism relevant to nanodevices and new spin-transfer torque random-access memory (STT-RAM), current-induced domain wall motion memory, and spin torque oscillators, as well as highly anisotropic materials and topics on magnetization damping are developed in detail in the book. New paradigms such as molecule-based magnets (MBMs), which are a promisingly adaptive class of solids poised to open new frontiers of exploration, are also covered. The relationship between magnetism and nonlinear optics and the new field of magnetoplasmonics is also developed in detail. The book also includes a thorough chapter on spin-polarized scanning tunneling microscopy (SP-STM), which enables studying magnetic phenomena on surfaces with real-space imaging and spectroscopy techniques down to the atomic level. All these topics are developed by an interdisciplinary team of leading experts in their pertinent fields. The book will certainly appeal to anyone involved in nanomagnetism and its application in spintronic nanodevices and nonlinear magneto-optics.

The concise and accessible chapters of Nanomagnetism and Spintronics, Second Edition, cover the most recent research in areas of spin-current generation, spin-calorimetric effect, voltage effects on magnetic properties, spin-injection phenomena, giant magnetoresistance (GMR), and tunnel magnetoresistance (TMR). Spintronics is a cutting-edge area in the field of magnetism that studies the interplay of magnetism and transport phenomena, demonstrating how electrons not only have charge but also spin. This second edition provides the background to understand this novel physical phenomenon and focuses on the most recent developments and research relating to spintronics. This exciting new edition is an essential resource for graduate students, researchers, and professionals in industry who want to understand the concepts of spintronics, and keep up with recent research, all in one volume. Provides a concise, thorough evaluation of current research Surveys the important findings up to 2012 Examines the future of devices and the importance of spin current

This first book to focus on the applications of nanomagnetism presents those already realized while also suggesting bold ideas for further breakthroughs. The first part is devoted to the concept of spin electronics and its use for data storage and magnetic sensing, while the second part concentrates on magnetic nanoparticles and their use in industrial environment, biological and medical applications. The third, more prospective part goes on to describe emerging applications related to spin current creation and manipulation, dynamics, spin waves and binary logic based on nano-scale magnetism. With its unique choice of topics and authors, this will appeal to academic as well as corporate researchers in a wide range of disciplines from physics via materials science to engineering, chemistry and life science.

The ?eld of Nanomagnetism is a young branch of the study of magnetic phenomena, phenomena that have been a source of amazement and stimulus for speculation for more than 3,000 years [1]. Nanomagnetism, despite being a young area, has already affected every sphere of human activity, through its fundamental contribution to make the computer an ubiquitous instrument for communication, control of industrial processes, medical diagnosis, scienti?c investigation, or leisure. The studies of particulate and thin ?lm magnetic media and other related questions led to improvements that have mul- plied, in ?ve decades, the amount of data that can be encoded into a unitary area by some 50 million times. The 2007 Nobel Prize in Physics, awarded to Albert Fert and Peter Grünberg, is an important recognition of the extraordinary achievements of the research in Na- magnetism. The unfolding revolution brought about by Spintronics is intimately c- nected, and enhances the relevance of these developments. Nanomagnetism already encompasses a very wide range of remarkable pr- erties and phenomena, as illustrated in the case of thin ?lms, for example, by the volumes of the series on Ultrathin Magnetic Structures [2].

III–V compound semiconductors such as GaAs and InAs alloyed with Mn exhibit ferromagnetism. The magnetic, electrical, and optical properties of ferromagnetic III–V semiconductors are first compiled along with the way to prepare the epitaxial films and the effect of postgrowth annealing. Theories available to explain the magnetism in these alloys are then presented. Because the ferromagnetic semiconductors are compatible with epitaxial III–V heterostructures, a number of device structures have been examined and shown to reveal a wide variety of phenomena that either cannot be realized or are very difficult to observe in ferromagnetic metal structures. The unique properties revealed by ferromagnetic semiconductor structures, ranging from reversible electric field control of ferromagnetic phase transition to generating velocity versus current-density curves of current-induced domain wall motion, are then reviewed. The prospect of realizing high-transition temperature is discussed in the last section.
