(Feb.4, '15) Skyrmions are candidates for future data storage and
information processing
Small magnetic whirls may revolutionize future data storage
and information processing if they can be moved rapidly and reliably in small
structures. A team of scientists of Johannes Gutenberg University Mainz (JGU)
and TU Berlin, together with colleagues from the Netherlands and Switzerland,
has now been able to investigate the dynamics of these whirls experimentally.
The skyrmions, as these tiny whirls are called after the British nuclear
physicist Tony Skyrme, follow a complex trajectory and even continue to move
after the external excitation is switched off.
