Invitation: Reception Final Assembly of HFM
Six years full of hard work with planning and constructing the High-Field Magnet for Helmholtz-Zentrum Berlin we are proud to inform you that the final assembly is now complete.
Before further test are going to start and the neutron beamline will be connected, we like to invite you to a reception at the lecture hall at the Helmholtz-Zentrum Berlin Wannsee on Thursday, July 10th at 11 am.
The reception includes short lectures from Dr. Peter Smeibidl (Project Manager HFM), Dr. Mark Bird (NHMFL Tallahassee) and Bernd Tibes (DGI Architects).
After a lunch buffet we provide a guided tour to see the High-Field Magnet and Technikum building and give you the opportunity to talk to the scientist and engineers.
Please get in contact with Stefanie Kodalle by July 8th to register for the reception and indicate if you want to use the shuttle service from Adlershof and return.
Please find attached a detailed programme in the download box.
- 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.
- Patterns of polar vortices in lead-free superlattices on siliconA team at HZB has, for the first time, reported polar vortices in (BaTiO3/SrTiO3)10 superlattices on silicon. These results expand the range of materials and substrates on which polar topological textures can occur and open up new options for incorporating complex ferroelectric states into silicon-based technologies.
- Spin waves inside a nano-oscillator imaged for the first timeFor the first time, researchers have directly imaged the magnetisation dynamics inside a spin Hall nano-oscillator — a nanoscale device that converts direct current into tunable microwave signals and is a promising building block for energy-efficient wireless communication and brain-inspired computing. A Swedish–German team led by the University of Gothenburg and Helmholtz-Zentrum Berlin (HZB) achieved this using time-resolved scanning transmission X-ray microscopy at the MAXYMUS instrument at BESSY II. The results, now published in Advanced Materials, reveal spin-wave features that had escaped previous, indirect measurement techniques.
