Abstract

The rapid pace of progress in the computer industry over the past 40 years has been based on the miniaturization of chips and other computer components. Further miniaturization, however, faces serious challenges, e.g., due to increasingly high-power dissipation. To continue at pace, the industry must go beyond incremental improvements and embrace radically new technologies. This book discusses a number of topics from a promising nanoscale technology known as spintronics (or magnetoelectronics) in which information is carried not by the electron’s charge, as in conventional microchips, but also by the electron’s intrinsic spin. Changing the spin of an electron is faster and requires less power than moving it. Therefore if a reliable way can be found to control and manipulate spins, spintronic devices could offer higher data processing speeds, lower electric consumption, and many other advantages over conventional chips including, perhaps, the ability to carry out radically new quantum computations.
