Data Erased By Magnetic Monopoles
2013-05-31 12:38:36

Technische Universitaet Muenchen A physical particle postulated 80 years ago, could provide a decisive step toward the realization of novel, highly efficient data storage devices. Scientists at the Technische Universitaet Muenchen (TUM), the Technische Universitaet Dresden and the University of Cologne found that with magnetic monopoles in magnetic vortices, called skyrmions, information can be written and erased. Iron filings strewn on a sheet of paper trace the field lines of a bar...

Saving Data In Vortex Structures

New physical phenomenon could drastically reduce energy consumption by computers Three years ago Professor Christian Pfleiderer and his team from the physics department at the TUM discovered an entirely new magnetic structure in a silicon manganese crystal — a grid of magnetic eddies. Together with the team of Professor Achim Rosch from the University of Cologne, he studied the properties of these eddies, so-called skyrmions, named after the British physicist Tony Skyrme, who...

With the help of neutrons, TUM physicists discover new ways to save data One of the requirements to keep trends in computer technology on track "“ to be ever faster, smaller, and more energy-efficient "“ is faster writing and processing of data. In the Dec. 17 issue of the journal Science, physicists at the Technische Universitaet Muenchen (TUM) and the Universitaet zu Koeln report results that could point the way to a solution. TUM physicists set a lattice of magnetic vortices in...
