Introduction to Spintronics

This book provides an accessible presentation of the quantum mechanical concept of spin and the rapidly expanding technology associated with its use in information processing devices and circuits. Featuring many new drill problems, this edition reflects the explosion of study in spin-related physics, addressing seven important physical phenomena with spintronic device applications. It discusses spintronics without magnetism, which allows one to manipulate spin currents by purely electrical means. It explores lateral spin-orbit interaction and its many nuances, as well as the possibility to implement spin polarizers and analyzers using quantum point contacts. It also introduces the concept of single-domain-nanomagnet-based computing.
