Using spin to replace or augment the role of charge in signal processing devices, computing systems and circuits may improve speed, power consumption, and device density in some cases—making the study of spinone of the fastest-growing areas in micro- and nanoelectronics. With most of the literature on the subject still highly advanced and heavily theoretical, the demand for a practical introduction to the concepts relating to spin has only now been filled. Explains effects such as giant magnetoresistance, the subject of the 2007 Nobel Prize in physics Introduction to Spintronics is an accessible, organized, and progressive presentation of the quantum mechanical concept of spin. The authors build a foundation of principles and equations underlying the physics, transport, and dynamics of spin in solid state systems. They explain the use of spin for encoding qubits in quantum logic processors; clarify how spin-orbit interaction forms the basis for certain spin-based devices such as spintronic field effect transistors; and discuss the effects of magnetic fields on spin-based device performance. Covers active hybrid spintronic devices, monolithic spintronic devices, passive spintronic devices, and devices based on the giant magnetoresistance effect The final chapters introduce the burgeoning field of spin-based reversible logic gates, spintronic embodiments of quantum computers, and other topics in quantum mechanics that have applications in spintronics. An Introduction to Spintronics provides the knowledge and understanding of the field needed to conduct independent research in spintronics.

The success of spintronics — the science and technology of storing, processing, sensing and communicating information using the quantum mechanical spin degree of freedom of an electron — is critically dependent on the ability to inject, detect and manipulate spins in semiconductors either by incorporating ferromagnetic materials into device architectures or by using external magnetic and electric fields. In spintronics, the controlled generation and manipulation of spin polarization in nonmagnetic semiconductors is required for the design of spin-sensitive devices ranging from spin-qubit hosts, quantum memory and gates, quantum teleporters, spin polarizers and filters, spin-field-effect-transistors, and spin-splitters, among others. One of the major challenges of spintronics is to control the creation, manipulation, and detection of spin polarized currents by purely electrical means. Another challenge is to preserve spin coherence in a device for the longest time or over the longest distance in order to produce reliable spintronic processors. These challenges remain daunting, but some progress has been made recently in overcoming some of the steepest obstacles. This book covers some of the recent advances in the field of spintronics using semiconductors.

Spintronics refers to the study of the intrinsic spin of the electron and its associated magnetic moment. It has potential applications in the area of data storage and transfer. Spintronic systems are prominently present in dilute magnetic semiconductors (DMS) and Heusler alloys. Some metal-based spintronic devices are tunnel magnetoresistance, spin-transfer torque and spin-wave logic devices. Non-volatile spin-logic devices that enable scaling are being widely studied. Spin-transfer and torque-based logic devices that use spins and magnets for information processes are also being developed. This book provides comprehensive insights into the field of spintronics. Such selected concepts that redefine this field have been presented herein. Coherent flow of topics, student-friendly language and extensive use of examples make this textbook an invaluable source of knowledge.
