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 ...
Reliable Preparation of High Quality Superconducting Thin MgB2 Films for Application

ZDRAVKOV, V.; SIDORENKO, A.; ROSSOLENKO, A.; RYAZANOV, V.; BDIKIN, I.; KRÖMER, O.; NOLD, E.; KOCH, Th.; SCHIMMEL, Th. (IOP Publishing, 2007)

Since the discovery of its superconductivity (J. Nagamatsu, N. Nakagawa, T. Muranka, et al., 2001, Nature, 410, 63), MgB2 attracts considerable attention. A number of groups have intensively tried to fabricate high-quality ...
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. ...
