Leggett's plasma resonances and two-gap structures in the CVCs of MgB break junctions a direct evidence for a two-gap superconductivity in MgB
Ya. G. Ponomarev, S. A. Kuzmichev, M. G. Mikheev +13
In the present investigation (2002) the current-voltage characteristics (CVCs) of break junctions in polycrystalline samples have been studied in the temperature range $4.2…
Experimental evidence of two-band behavior of MgB2
Ya. G. Ponomarev, S. A. Kuzmichev, M. G. Mikheev +14
The break-junction tunneling has been systematically investigated in MgB2. Two types of the break-junction contacts have been exploited on the same samples, which demonstrated tunn…
Perspectives of superconducting MgB2 for microwave applications
Matthias A. Hein
We discuss the temperature, frequency, and power-dependent surface resistance of the boride superconductor MgB2 in relation to possible applications for passive microwave devices.…
Anomalous Nonlinear Microwave Response of Epitaxial YBa2Cu3O7-x Films on MgO
M. A. Hein, P. J. Hirst, R. G. Humphreys +2
We have investigated the anomalous nonlinear microwave response of epitaxial electron-beam coevaporated YBa2Cu3O7-x films on MgO. The power and temperature dependent surface impeda…
