The Leibniz Institute for Solid State and Materials Research Dresden (IFW) and Helmholtz-Zentrum Berlin (HZB) have created a Joint Lab for “functional quantum materials” and under its umbrella a Young Investigator Group.
The Joint Lab "Functional Quantum Materials" will take advantage of the long-standing expertise of both institutes in energy and materials research and the growth of epitaxial films.
The new lab is dedicated to explore new materials with promising quantum properties for future applications, for instance in information technologies. The scientists will further develop the common instrumentation at BESSY II with its unique properties - part of them without rival in the world.
With the joint lab, IFW Dresden and HZB intensify their collaboration in research and the promotion of young scientists. Dr. Alexander Fedorov, aged 29, is an internationally renowned young scientist who will move from Cologne to Berlin to head the Young Investigator Group.
- Only at BESSY II worldwide: IR nanoscopy at very long THz wavelengthsThe team at the IRIS beamline at BESSY II has created a new experimental option: They achieved infrared nanoscopy with a spatial resolution of around 50 nm at very long THz wavelengths. This was possible thanks to a temporal pattern of light pulses known as the low-alpha operating mode at BESSY II. Worldwide, BESSY II is the only synchrotron light source at which users could perform nanoscopy in a single setup from 25 to 4000 cm-1, a unique opportunity for ultra-broadband characterisation of complex materials at the nanoscale in both the life sciences and materials sciences.
- Ultrafast demagnetisation - Thinner iron, stronger effectThe thinner an iron film, the more easily it can be demagnetised by a laser pulse. Researchers at the University of Duisburg-Essen, working with Helmholtz-Zentrum Berlin and other partners, have discovered why: the key lies in the magnetic order at the material's interfaces. In the long term, these findings could contribute to the development of new technologies for magnetic data storage. The results have been published in the scientific journal Advanced Science.
- Blind spot for the arrangement of atomsArtificial intelligence is increasingly being used to predict the properties of new materials. A research team from Jena and the United States now shows in a study published in the journal Nature Computational Science that when language models are used for this purpose, they reliably identify which types of atoms a material contains. However, they make insufficient use of information about how those atoms are arranged in space. Neither larger models nor additional training data resolve this weakness. For material properties that depend strongly on structure, AI models specifically designed to process spatial relationships are therefore the more reliable choice. (DOI: 10.1038/s43588-026-01045-2)
