Current Highlights and News
Employing a tailored multilayered magnetic film, optimized for the zero-field stabilization of magnetic skyrmions, researchers have investigated the influence of the skyrmion diameter on its current-induced sideways motion, uncovering mechanisms that allow for this topological property to be controlled.
3D imaging using synchrotron radiation is a widely used tool that allows access to the inner structure of complex objects. An international and interdisciplinary consortium of scientists from the Swiss Light Source (PolLux and cSAXs), the Friedrich-Alexander-Universität Erlangen-Nürnberg, and the University of Cambridge developed the new 3D imaging technique of Soft X-ray Laminography (SoXL). SoXL allows for the investigation of thin and extended samples while taking advantage of the characteristic absorption contrast mechanisms in the soft X-ray range, providing 3D information with nm spatial resolution.
Researchers in a joint collaboration between the PolLux endstation of the Swiss Light Source and the University of Leeds have achieved the reliable and reproducible electrical nucleation of magnetic skyrmions from a nano-engineered point contact structure, investigating the physical mechanisms driving the nucleation process.
