Current Highlights and News
HERCULES school 2019 at SLS
In the week of April 1-5 PSI welcomes 20 PhD students and postdocs taking part in the European HERCULES 2019 school on Neutron and Synchrotron Radiation. They will attend lectures and perform two days of practical courses at several beam lines of the Swiss Light Source.
Sub-ns magnetic domain wall motion dynamics
Magnetic domain walls can be reliably displaced by electrical currents, allowing for the fabrication of retentive magnetic memory elements without mechanically moving parts, such as e.g. the magnetic racetrack memory. Researchers in a joint collaboration between the PolLux endstation of the Swiss Light Source and the University of Leeds were able to investigate the dynamics of magnetic domain wall motion with a sub-ns time step, providing a substantial step forward towards the unraveling of the physical processes behind the current- and magnetic field-induced motion of magnetic domains.
Discrete Hall contribution of magnetic skyrmions
The reliable electrical detection of magnetic skyrmions is of fundamental importance for the application of such topological magnetic quasi-particles for data storage devices. Researchers in a joint collaboration between the University of Leeds and the PolLux endstation have investigated the electrical detection of isolated magnetic skyrmions in applications-relevant nanostructured devices, observing the presence of a strong skyrmion-dependent contribution to the Hall resistivity.
