Giant Magneto-Resistance Devices

In the last decade after the discovery of "giant magnetoresistance effects" in me­ tallic multilayers worldwide developments in basic research and in engineering applications have been achieved, and various remarkable results have been ob­ tained in both fields. On the basic research into the GMR effects an excellent re­ view book edited by Hartmann was published in 1999, entitled "Magnetic Multi­ layers and Giant Magnetoresistance", and it describes the experimental and theoretical aspects...
