Transmission x-ray microscopy at low temperatures - analyzing supercurrents with high spatial resolution
J. Simmendinger, S. Ruoss, C. Stahl +4
Scanning transmission x-ray microscopy has been used to image electric currents in superconducting films at temperatures down to 20 K. The magnetic stray field of supercurrents in…
The temperature-dependent magnetization profile across an epitaxial bilayer of ferromagnetic La2/3Ca1/3MnO3 and superconducting YBa2Cu3O7-d
S. Brück, S. Treiber, S. Macke +6
Epitaxial bilayers of ferromagnetic La2/3Ca1/3MnO3 (LCMO) and superconducting YBa2Cu3O7-d (YBCO) have been grown on single-crystalline SrTiO3 (STO) substrates by pulsed laser depos…
Superconducting phase formation in random neck syntheses: a study of the Y-Ba-Cu-O system by magneto-optics and magnetometry
J. B. Willems, J. Albrecht, I. L. Landau +1
Magneto-optical imaging and magnetization measurements were applied to investigate local formation of superconducting phase effected by a random neck synthesis in Y-Ba-Cu-O system.…
Universal temperature scaling of flux line pinning in high-temperature superconducting thin films
J Albrecht, M Djupmyr, S Bruck
Dissipation-free current transport in high-temperature superconductors is one of the most crucial properties of this class of materials which is directly related to the effective i…
Dramatic role of critical current anisotropy on flux avalanches in MgB2 films
J. Albrecht, A. T. Matveev, J. Strempfer +4
Anisotropic penetration of magnetic flux in MgB2 films grown on vicinal sapphire substrates is investigated using magneto-optical imaging. Regular penetration above 10 K proceeds m…
Spin-polarized quasiparticle injection effects in YBCO thin films
S. Soltan, J. Albrecht, H. -U. Habermeier
We report detailed transport studies on ferromagnet-superconductor heterostructures. Epitaxial heterostructures of half-metal colossal magnetoresistive La2/3Ca1/3MnO3 (HM-CMR) and…
