    “VEKMAG” at BESSY II creates 3D magnetic fields in samples

    Together with HZB, teams from the Universität Regensburg, from the Freie Universität Berlin and from  the  Ruhr Universität Bochum have jointly set up a unique measurement station at BESSY II: a vector electromagnet consisting of three mutually perpendicular Helmholtz coils which enables setting the local magnetic field at the sample position to any orientation desired.

    Universality of charge order in cuprate superconductors

    Charge order has been established in another class of cuprate superconductors, highlighting the importance of the phenomenon as a general property of these high-Tc materials. [...].

    Self-assembly of gold nanoparticles into small clusters

    Researchers at HZB in co-operation with Humboldt-Universität zu Berlin have made an astonishing observation: they were investigating the formation of gold nanoparticles in a solvent and observed that the nanoparticles had not distributed themselves uniformly, but instead were self-assembled into small clusters.

    Neutron Tomography technique reveals phase fractions of crystalline materials in 3-Dimensions

    Researchers at Helmholtz-Zentrum Berlin and the University of Tennessee Knoxville have developed a novel method, based on energy-selective neutron imaging for visualization of crystalline phase distributions within the bulk of metallic samples. The method overcomes limitations of existing techniques and allows a 3-D representation of the phase fractions within the sample volume. [...].

      New and improved short-time measurements

      A team around Gregor Schiwietz at HZB has developed a new kind of spectrometer capable of particularly sensitive analyses of sample surfaces. It has allowed them to be the first to obtain measurements of a copper sample's Auger electron spectrum at the HZB's synchrotron radiation source BESSY II's femtoslicing beamline at extremely high temporal resolutions.
