The ASC advances the science and technology of superconductivity and particularly superconductivity applications. We do this by investigating low temperature and high temperature materials through our research grants and through our collaborations with other universities, national laboratories and industry. We continually educate post-graduate, graduate and undergraduate students by our research and public service.

  • Evidence for extrinsic, impurity segregation at grain boundaries in high current-density K- and Co-doped BaFe2As2

    Evidence for extrinsic, impurity segregation at grain boundaries in high current-density K- and Co-doped BaFe2As2

    Grain boundaries in BaFe2As2 (122), which is an iron-based superconductor, block current flow. This study, which was a collaboration with a group at Northwestern University, used a Local Electrode Atom Probe (LEAP), which is a relatively new experimental tool, to make a 3-D atom-by-atom reconstruction of a region of a 122 sample that included a grain boundary. The data showed that the chemical composition varied across the grain boundary and in that oxygen was present at the grain boundaries. These variations in composition may contribute to grain boundary's reduced current carrying capacity.
