The ULTRASWITCH network addresses the field of ultra fast switching phenomena in magnetic submicron structures for applications such as magnetic sensors, magnetic random access memory elements and media for magnetic recording. It provides advancement of science, development of new routes for ultra fast switching and the training of 12 - 1 7 young researchers to provide the work force for tomorrows research, development and production in Europe in a strongly expanding field. The strong demand for continuing increase of data storage density and access time poses a strong challenge in particular on the exploration and development of new schemes for ultra fast applications. This can only be achieved by a combined action of the leading research groups in this field strongly inter-linked with leading industry. The ULTRASWITCH network comprises seven leading laboratories and three industrial companies to meet this challenge. The network is aimed to overcome the severe switching speed problems in devices, caused by the crossing of the access rate with fundamental time scales, such as the precession frequency. It focuses on coherent switching phenomena as the projected most successful path to stable magnetic switching in sub-nanosecond applications. As one example, in the area of magnetic random access memory, the ULTRASWITCH network will contribute to the scientific background to ultra fast memory designs in future memory applications.
