First Experimental Demonstration of Antiskyrmions

Tiny magnetic vortex structures in materials, called skyrmions, were first detected experimentally a good 10 years ago. Today, they form a basis for innovative concepts in information processing with better performance and less energy consumption. Furthermore, skyrmions influence the electronic and thermodynamic properties of a material. Because of their relevance for both applied and fundamental research, skyrmions are the subject of numerous scientific investigations worldwide and also at Forschungszentrum Jülich. Jülich scientists, together with colleagues at RWTH Aachen University and the University of Uppsala in Sweden, have now experimentally demonstrated anti-skyrmions for the first time.

The two JARA-FIT scientists Prof. Stefan Blügel and Prof. Rafal Dunin-Borkowski were significantly involved in the investigations. The results were published in the scientific journal nature physics. Jülich theoretical physicist Dr. Nikolai Kiselev, a research associate at the Peter Grünberg Institute and the Institute for Advanced Simulations, is part of the team that succeeded in proving the discovery; in an interview, he explains the significance of the findings.
