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;
• Tutorial chapters that explains the required physics (domain theory, spin waves) and motivates the study of magnetic devices;
• Focuses on logic and computing applications of magnetics.
