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.
- Martin Keller elected new president of the Helmholtz AssociationThe Helmholtz Association has appointed internationally respected US-based scientist Martin Keller as its new president. Her has lived in the United States for nearly three decades, during which he has held various scientific leadership roles at prominent institutions. Since 2015, Keller has directed the National Renewable Energy Laboratory (NREL) in Golden, Colorado. His term begins on 1.11. 2025.
- Alternating currents for alternative computing with magnetsA new study conducted at the University of Vienna, the Max Planck Institute for Intelligent Systems in Stuttgart, and the Helmholtz Centers in Berlin and Dresden takes an important step in the challenge to miniaturize computing devices and to make them more energy-efficient. The work published in the renowned scientific journal Science Advances opens up new possibilities for creating reprogrammable magnonic circuits by exciting spin waves by alternating currents and redirecting these waves on demand. The experiments were carried out at the Maxymus beamline at BESSY II.
- BESSY II: Heterostructures for SpintronicsSpintronic devices work with spin textures caused by quantum-physical interactions. A Spanish-German collaboration has now studied graphene-cobalt-iridium heterostructures at BESSY II. The results show how two desired quantum-physical effects reinforce each other in these heterostructures. This could lead to new spintronic devices based on these materials.
