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.

    Spintronics by “straintronics”: Superferromagnetism with electric-field induced strain

    Data storage in today’s magnetic media is very energy consuming. Combination of novel materials and the coupling between their properties could reduce the energy needed to control magnetic memories thus contributing to a smaller carbon footprint of the IT sector. Now an international team led by HZB has observed at the HZB lightsource BESSY II a new phenomenon in iron nanograins: whereas normally the magnetic moments of the iron grains are disordered with respect each other at room temperature, this can be changed by applying an electric field: This field induces locally a strain on the system leading to the formation of a so-called superferromagnetic ordered state.

    Batteries with silicon anodes: Neutron experiments show how formation of surface structures reduces amp-hour capacity

    In theory, silicon anodes could store ten times more lithium ions than graphite anodes, which have been used in commercial lithium batteries for many years. However, the amp-hour capacity of silicon anodes so far has been declining sharply with each additional charge-discharge cycle. Now an HZB team at BER II of the HZB in Berlin and the Institut Laue-Langevin in Grenoble has utilised neutron experiments to establish what happens at the surface of the silicon anode during charging and what processes reduce this capacity.

    New insights into magnetic quantum effects in solids

    Using a new computational method, an international collaboration has succeeded for the first time in systematically investigating magnetic quantum effects in the well-known 3D pyrochlore Heisenberg model. The surprising finding: physical quantum phases are formed only for small spin values. [...]
