Spin-Based Computing Devices

This book provides readers with a single-source reference to the state of the art in domain-wall, nanomagnet and spin-wave-based computing devices, enabling them to provide additional computing functions and lower the power consumption of electronic devices by orders of magnitudes. Tutorial chapters gives a thorough introduction to the preliminaries and the theory behind spin-based devices, and additional chapters give an overview of the most promising spin-based computing concepts. This book is designed to be a 'first read' for anyone interested in the field of spin-based (magnetic) computing devices. The author provides an overview of how information can be processed by single-domain nanomagnets, domain walls, spin-waves or spin torque oscillators. Both Boolean approaches (magnetic logic gates) and non-Boolean devices (image processing circuits, etc.) are discussed.

Provides content accessible to an engineering audience in need of information about the physics of domain-wall, nanomagnet and spin-wave-based computing devices Begins with long tutorial chapter that explains the required physics (domain theory, spin waves) and motivates the study of magnetic devices Focuses on logic and computing applications of magnetics
