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…

Enhancement of flux-line pinning in all-oxide superconductor/ferromagnet heterostructures
H. -U. Habermeier, J. Albrecht, S. Soltan
We have studied the local critical current density, jc, in the superconductor thin film of bilayer structures consisting of YBa2Cu3O7 and the ferromagnets La2/3Ca1/3MnO3 and SrRuO3…
