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…
Recent developments in the characterization of superconducting films by microwaves
M. A. Hein, M. Getta, S. Kreiskott +7
We describe and analyze selected surface impedance data recently obtained by different groups on cuprate, ruthenate and diboride superconducting films on metallic and dielectric su…
Dependence of the gap parameter on the number of CuO2 layers in a unit cell of optimally doped BSCCO, TBCCO, HBCCO and HSCCO
Ya. G. Ponomarev, N. Z. Timergaleev, A. O. Zabezhaylov +8
We have measured the superconducting gap Ds in optimally doped samples of BSCCO, TBCCO, HBCCO and HSCCO by Andreev and tunnelling spectroscopy and by ARPES. We have found that the…
Superconducting properties of La-substituted Bi-2201 crystals
Ya. G. Ponomarev, N. Z. Timergaleev, Kim Ki Uk +8
The superconducting gap Delta has been measured in Bi2Sr2-xLaxCuO6+d single crystals in a wide range of temperatures 4.2 K < T < Tc by point-contact and tunnelling spectroscopy for…
