Magnetic solids can demagnetize upon heating. Despite decades of research, it has so far been unclear how this process works in detail. Now, for the first time, an international group has observed in a step-by-step manner how sudden heating affects the magnetic order of a ferrimagnetic insulator on two different time scales. The work is published in Science Advances. [...].
At the International Conference on Thermoelectrics in July in Caen, France, Dr. Katherine Ann Mazzio from the HZB Institute of Nanospectroscopy received a prize for her poster. The conference is the world's largest symposium on thermoelectric materials. [...].

Young people from all over the world have applied to the Helmholtz Centre to take part in the annual summer programme: eight weeks of research in an HZB team, well supervised, taking their first steps in their own scientific work. Now 21 students from eleven countries have arrived and are looking forward to their research project. They will present their results on 30 August. [...].
Hydrogen will play a central role as a storage medium in sustainable energy systems. An international team of researchers has now succeeded in raising the efficiency of producing hydrogen from direct solar water-splitting to a record 19 per cent. They did so by combining a tandem solar cell of III-V semiconductors with a catalyst of rhodium nanoparticles and a crystalline titanium dioxide coating. Teams from the California Institute of Technology, the University of Cambridge, Technische Universität Ilmenau, and the Fraunhofer Institute for Solar Energy Systems ISE participated in the development work. One part of the experiments took place at the Institute for Solar Fuels in the Helmholtz-Zentrum Berlin. [...].

HZB researcher introduces unique operando characterization by soft X-ray spectroscopy
The HZB physicist Raül Garcia Diez has been awarded a poster prize at the international conference "Synchrotron Radiation Instrumentation 2018" (SRI 2018) in Taiwan. He presented how the HZB team intends to observe the reactions in electrocatalysts under "operando" conditions with soft X-rays from BESSY II. [...].
After further optimization of the baseline process for industrial silicon heterojunction (SHJ) solar cells, the accredited metrology lab ISFH CalTeC now certified an efficiency of 23.1 % for a 4 cm² solar cell. This performance is among the best in the world and demonstrates the leading role of HZB in this technology in Germany and Europe.
