The book discusses almost all aspects of spintronics-based neuromorphic computing, starting froma very basiclevel, and willbe of interest toboth spintronics and neuromorphic computing communities. The chapters also cover most simulation and experimental studies reported recently by researchersworldwideon this topic. The book includes an introductory chapter on nanomagnetism and spin physics and another on neural network algorithms (covering both the machine-learning and neuroscience aspects of these algorithms).These introductory chapters will help the readers build their background andtrulyappreciate the recent research results on spintronics-based neuromorphic computing, presented in thelater chapters of the book.Various numerical simulation exercisesare also providedin the book.
