The Executive Board of the European Microscopy Society (EMS) has received the decision of the Jury of the EMS Outstanding Paper Award for the year 2021. In total 21 high quality papers were nominated by EMS members. Of these, three were selected as award winners in the categories "Instrumentation and Technique Development", "Materials Sciences" and "Life Sciences". In “Materials Sciences”, the prestigious award goes to a recent Nature publication (co-)authored by and with significant contributions from scientists of the Dresden Center for Nanoanalysis (DCN):

Daniel Wolf, Sebastian Schneider, Ulrich K. Rößler, András Kovács, Marcus Schmidt, Rafal E. Dunin-Borkowski, Bernd Büchner, Bernd Rellinghaus and Axel Lubk, Unveiling the three-dimensional magnetic texture of Skyrmion tubes, Nature Nanotechnology 17 (2022) 250–255 (online December 2021). The two first authors contributed equally. https://doi.org/10.1038/s41565-021-01031-x

The paper was nominated by Prof. Dr. Michael Lehmann, Technical University Berlin, Germany:

“The authors have extended the transmission electron microscopy based approach of holographic vector field electron tomography to low temperatures and to concurrently exposing the sample to an external magnetic field. They have used this novel technique to determine the magnetic structure of metastable skyrmion tubes in FeGe quantitatively in 3D with unequaled resolution. The obtained quantitative data of the 3D magnetic induction field has allowed the authors to experimentally identify a variety of previously unseen details in the magnetic texture of the skyrmion tubes and for the first time shown experimental evidence for the energetic stabilization of the skyrmion tubes. The work reveals microscopic details that are expected to have a strong impact on the understanding of the interaction between skyrmion tubes in real structures. The paper serves as an impressive example as to how modern microscopy approaches may contribute significantly to the understanding of emerging materials and phenomena with a large potential to nourishing new technical applications.”

The work will be presented at the Seventh Conference on Frontiers of Aberration Corrected Electron Microscopy PICO 2022 on 8th May 2022.
