  • Change of the effective dimensionality of an Nb/CuNi bilayer in an external magnetic field 
    KEHRLE, J.-M.; ZDRAVKOV, V.; MORARI, R.; PREPELITSA, A.; MÜLLER, C.; WIXFORTH, A.; HORN, S.; TIDECKS, R.; SIDORENKO, A. (IOP Publishing, 2009)
    A dimensional crossover of superconducting fluctuations in an external magnetic field, applied parallel to the layers, has been found for superconductor/ferromagnet bilayers of Nb/Cu41Ni59. By lowering the temperature, a ...
  • Influence of strong disorder on superconductivity of MgB2 thin films 
    KOCH, Th.; ZDRAVKOV, V. I.; SURDU, A.; CONDREA, E.; SOCROVISCIUC, A.; ROSSOLENKO, A. N.; RYAZANOV, V. V.; STRAUMAL, B.; TIDECKS, R.; WIXFORTH, A.; SIDORENKO, A. S. (Institutul de Inginerie Electronică şi Nanotehnologii "D. Ghiţu", 2008)
    We investigated the influence of disorder on superconductivity of MgB2 films, prepared in a single deposition run onto two different substrates: (100)-MgO and on (128° rot)-LiNbO3 with trigonal crystal structure which ...
  • Thermally assisted flux flow and melting transition for Mo/Si multilayers 
    SIDORENKO, A.; ZDRAVKOV, V.; RYAZANOV, V.; HORN, S.; KLIMM, S.; TIDECKS, R.; WIXFORTH, A.; KOCH, Th.; SCHIMMEL, Th. (Taylor & Francis, 2005)
    The origin of the resistive transition broadening of superconducting MgB2 thin films is investigated. Thermally activated flux flow is found to be responsible for the resistivity in the vicinity of the critical temperature. ...
  • Two-Dimensional Superconducting Fluctuations in MgB2 Films 
    SIDORENKO, A. S.; ZDRAVKOV, V. I.; RYAZANOV, V. V.; KLEMM, M.; HORN, S.; TIDECKS, R.; MÜLLER, C.; WIXFORTH, A. (Springer Nature Switzerland, 2004)
    The origin of the resistive transition broadening for superconducting MgB2 films is investigated experimentally. The crucial role of two-dimensional weak and critical fluctuations is demonstrated.
