Book excerpt: Symposium T, "Materials for Magnetic Devices--Magneto-Electronics and Recording," held April 16-19 at the 2001 MRS Spring Meeting in San Francisco, California, highlighted the exciting new area of spintronics and its applications to recording, sensors, and quantum computing. It covered new materials and structures that use the mechanism of spin dependent transport, including giant magnetoresistive (GMR) materials and magnetic tunnel junctions (MTJs). Symposium U. Ferromagnetic materials are used in a wide variety of applications, including permanent magnets, transformer cores, electrical generators, and magnetic data storage. In the past decade there have been unprecedented developments; in ferromagnetic materials, resulting in much-improved magneto-optical, magneto-resistive, magnetostrictive, permanent and nanocrystalline soft magnetic materials. Symposium V. CD and DVD technologies are pervasive throughout society and they are one of the success stories involving optical materials and devices. Technology roadmaps predict storage capacities exceeding 100 GB for DC size removable disks, using blue lasers and optics with high light-collection efficiency for the second half of this decade. Larger storage capacities require commensurately faster data recording and readout rates.
