News/Highlights

Robbie Hunt from Uppsala University (20.04.-06.05.2026) and Raluca Boltje from Augsburg University (05.05.-08.05.2026) visited our group at TUC to perform in situ MOKE measurements on their samples and give seminar talks. It was a very fruitful scientific exchange.

At the IEEE International Magnetics Conference (INTERMAG 2026) in Manchester, Karin gave an invited talk on recent advances in magneto-ionics, and Markus, Anna, and Felix presented their latest results.

Our systematic study on the Low-Voltage Controlled Coercivity in Nanocrystalline Fe-Ni Films by Magneto-Ionic Effects is published in Advanced Electronic Materials. Congratulation to Anna!

Our collaborative work with the TU Graz and the Leibniz IFW Dresden on the Additive-enhanced hydrogen- and hydroxide-based magneto-ionic control in Ni films is published in Physical Review Materials. Congratulation to Maksim, Markus and Stefan!

During the joint Seminar in the Saxon Switzerland, funded by the W.E. Heraues foundation, the MagFun group (Prof. O. Hellwig, Institute of Physics) and the ELSEN group (Prof. K. Leistner, Institute of Chemistry) intensified their interdisciplinary collaboration by exciting talks on available techniques and research topics in both teams. Successfull teambuilding was achieved during several hiking tours and a games night.

Francesca Sgarbi Stabellini successfully finished her PhD with the disputation of her thesis on Electrodeposition of Copper in Magnetic Field Gradients of Micrometer- to Nanometer-size Templates. Congratulation!

At the 76th Annual Meeting of the International Society of Electrochemistry in Mainz, Anna presented her latest poster entitled “Reversible electrochemical control of coercivity in electrodeposited Fe-Ni alloy films,” while Martin gave a presentation on the topic “Impact of the Electrolyte Composition on the Self-Termination Mechanism During Nanoscale Iron Oxide/Iron Electrodeposition.”

At the 14th Joint European Magnetic Symposia in Frankfurt am Main, Markus presented his latest paper with the title: “Reversible magneto-ionic control of exchange bias in spin-valve-like heterostructures.” Anna gave a presentation on the topic: Enhancing Magneto-ionic Effects in Nickel-Iron Films by tuning the Alloy Composition, while Felix talked about his poster: “Speeding up hydrogen magneto-ionics in Co/Pd multilayers.”

Our collaborative work with the University of Kassel and the Leibniz IFW Dresden on the reversible control of exchange bias in an IrMn/Fe/Au/Fe spin-valve-like heterostructure is published in ACS Applied Materials & Interfaces. Congratulation to Markus!

During our Team day we had exciting talks from group members, updating everyone on the current topics. The day continued with a  visit to the exhibition on Saxon innovations at the university library and a great joint evening at the Weinfest Chemnitz.

Markus presented a talk on the magneto-ionic control of exchange bias in IrMn/Fe/Au/Fe at the 12th International Symposium on Metallic Multilayers in Leeds, UK.

Martin, Anna and Francesca presented talks on magnetoelectrodeposition, magneto-ionics and self-terminated electrodeposition at the 16^th International Workshop on Electrodeposited Nanostructures (EDNANO) in Florence, Italy.

We had an exciting DPG spring meeting in Regensburg, with fruitful networking within the physics community. Markus gave an invited talk on hydrogen-magneto-ionics, Anna presented a talk on magneto-ionics in Fe-Ni alloys and Danny presented a poster on epitaxial Fe deposition.

Our collaborative work with the Leibniz IFW Dresden and the HZDR on Downscaling magnetic field gradients for structured copper magnetoelectrodeposition on the micrometer scale is published in Electrochimica Acta. Congratulation Francesca!

After successful negotiations to stay at Chemnitz University of Technology, Karin was appointed as W3 professor for electrochemical sensing and energy storage.

Karin gave a keynote lecture on Electrochemistry meets Magnetism at the first Hydrogen Energy Symposium in Duisburg, organized by the hydrogen and fuel cell center ZBT.

Martin Nichterwitz successfully finished his PhD time with the disputation of his thesis on Electrochemical synthesis and magneto-ionic control of magnetization and magnetoresistance in iron-based thin films and 3D structures. Congratulation!
