This text is the culmination of a summer school on spintronics, held in August 1998, in Lake Tahoe, Nevada, that brought together experts on all aspects of magnetism and spin transport phenomenon. These experts lectured for one week on this emerging and important field of study. What was a fledgling field in 1998 has become one of the fastest growing areas of science in less than five years, having impact in many areas of information technology. This book is a collection of some of the lectures that were presented, updated to provide the most up-to-date information on the topics that are covered in the various chapters.
