Host: Albert Chang

Abstract: Conventional electronic devices exploit the charge of the electron. Recently, devices have started to exploit the electron's spin. A particular success is the read head used in high-density magnetic recording, where only ten years passed between the basic laboratory discovery and its application in commercial devices. In this talk, I survey the basic physics of spintronics in metallic systems, where most applications have been made. The basic ingredients are newly-discovered and non-classical effects of magnetism on current flow and of current flow on magnetism. This latter effect can lead to current-induced magnetization reversal and high frequency precession.
