International Conference in Neutron Scattering: HZB-contributions awarded
Dr. Anup Kumar Bera from the department of Quantum Phenomena in Novel Materials convinced the committee with his poster about ‘Haldane chains’.
More than 800 participants had gathered for the International Conference in Neutron Scattering, held during 8-12 July 2013 in Edinburgh, to discuss advances in neutron research and the advancement of the neutron scattering instruments and techniques. A committee selected sixteen outstanding posters from the 650 poster presentations, two of these from HZB scientists.
Dr. Anup Kumar Bera from the department of Quantum Phenomena in Novel Materials convinced the committee with his poster about quantum magnetic properties in a one dimensional spin-1 chain magnet known as ‘Haldane chain’. When cooled down to low temperature, this material hosts a fascinating state of matter called a “quantum spin-liquid”.
Matthew Barrett received a poster prize for the best student poster contribution. He is a PhD-student at F-ISFM and works as well in the department fpr sample environment, where he optimizes humid environment cells for biological samples.
Dr. Elisa Wheeler received the Young Scientist Award from the International Union of Cristallography. The jury awarded her research work, which she completed as a postdoctoral student with Prof. Bella Lake and Dr. Nazmul Islam at the HZB. Elisa Wheeler is now a scientist at the Institut Laue-Langevin in Grenoble, Frankreich.
- Spintronics at BESSY II: Real-time analysis of magnetic bilayer systemsSpintronic devices enable data processing with significantly lower energy consumption. They are based on the interaction between ferromagnetic and antiferromagnetic layers. Now, a team from Freie Universität Berlin, HZB and Uppsala University has succeeded in tracking, for each layer separately, how the magnetic order changes after a short laser pulse has excited the system. They were also able to identify the main cause of the loss of antiferromagnetic order in the oxide layer: the excitation is transported from the hot electrons in the ferromagnetic metal to the spins in the antiferromagnet.
- Too old for research at 60? From nuclear physics to papyrus researchA career in science can be personally fulfilling. However, this also means accepting the unpredictable: research topics may no longer receive funding, and laboratories may close. Heinz-Eberhard Mahnke experienced this first-hand when he had to seek new challenges in his early 60s. Today, the 81-year-old is still active in research, using non-destructive measurement methods to examine ancient artefacts of inestimable cultural value. Antonia Rötger spoke with this extraordinary researcher, whose curiosity and drive are truly inspiring.
- A duo for BESSY III light sourceSince 1 March 2026, Renske van der Veen and Andreas Jankowiak have formed the leadership team of BESSY III. Together, they will drive forward HZB’s central project: the planning and realisation of BESSY III light source in Berlin-Adlershof. Here, they talk about their motivation, the next steps, and why BESSY III is a a cross-generational project.
