Synopsis:
‚Spin-torque transfer’ describing the angular momentum transfer between a spin-polarized electric current and local magnetic moments has been theoretically predicted in 1996 by Berger and independently by Slonczewski. Since the experimental verification of current-induced magnetization precession by Tsoi et al. in 1998 and of current-induced magnetization switching by Katine et al. in 2000, spin-torque mediated magnetization dynamics have moved into the focus in the framework of current-driven magnetic storage devices. In this context the effect was suggested to be of great use in improving the performance of magnetic random access memory (MRAM) or even to provide an approach to fabricate completely new storage technologies like the so-called ‘Racetrack Memory’. Despite the promising results obtained so far, the final step towards application still is out of sight. An example of the difficulties which hinder device fabrication at present is the large current density needed to switch magnetizations or move domain walls. It is the goal of the workshop to show recent progress and new approaches on how spin-torque driven magnetization dynamics (magnetization reversal, magnetization precession (microwave oscillators), domain-wall movement) can be studied, influenced and microscopically be understood.

The workshop will be held in the Wolfsburg. The building is located near to the river Ruhr – in the middle of one of the most densely populated metropolitan areas of Europe – within a large forest located between the cities of Duisburg and Mulheim an der Ruhr and near to Dusseldorf, Essen and Oberhausen. The area is host to the European
Capital of Culture RUHR 2010
offering almost daily cultural events and highlights during the year.
In 1906 constructed, the building served as an exclusive hotel. The name („wolfs castle“ ) reflects the existence of wolfs in the surrounding forests till the beginning of the 19th century. Since 1960 it serves as a modern venue for workshops and seminars within walking distance of the campus of the university of Duisburg-Essen.

Arrival by train: Main Railway station “Duisburg Hauptbahnhof” (www.bahn.de), Tram 901 direction “Mulheim an der Ruhr”.

Arrival by Plane: Airport Dusseldorf (DUS) and taxi (about 30 €) or Airport Frankfurt and high speed train (ICE) to “Duisburg Hauptbahnhof”
