Group Retreat 2026

Our annual group retreat took place on September 14–15, 2026. The purpose of this event was both to facilitate informal discussions on scientific topics and to strengthen the team spirit within the group.

3DMAG Symposium in Vienna

ICMF Conference in Vienna

Yahya Shubbak, Nikolai Weidt, and Rico Huhnstock attended the 17th International Conference on Magnetic Fluids (ICMF-17) in Vienna, Austria, from July 5–10, 2026. Among other topics, the conference addressed therapeutic approaches for treating cancer using magnetic particles.

From June 22 to June 26, 2026, Arne Vereijken, Jonas Bugase, and Mika Ossenschmidt attended the European Conference PHYSICS OF MAGNETISM 2026 (PM'26) in Poznań, Poland. Arne Vereijken and Mika Ossenschmidt each presented a poster on magnetic interface effects. Jonas Bugase gave a presentation on the use of geometrically structured magnetic particles to characterize magnetic stray field landscapes. The conference was opened by Klaus von Klitzing, who was awarded the Nobel Prize in Physics in 1985 for the discovery of the quantized Hall effect.
