Observation of a Transition from BCS to HTSC-like Superconductivity in Ba_{1-x}K_xBiO_3 Single Crystals
G. E. Tsydynzhapov, A. F. Shevchun, M. R. Trunin +4
A study of temperature dependences of the upper critical field B_{c2}(T) and surface impedance Z(T)=R(T)+iX(T) in Ba_{1-x}K_xBiO_3 single crystals that have transition temperatures…
Fractional quantum Hall effect without energy gap
S. S. Murzin, S. I. Dorozhkin, G. E. Tsydynzhapov +1
In the fractional quantum Hall effect regime we measure diagonal () and Hall () magnetoresistivity tensor components of two-dimensional electron system (2DES) in ga…
Temperature and Frequency Dependence of Complex Conductance of Ultrathin YBa2Cu3O7-x Films: A Study of Vortex-Antivortex Pair Unbinding
V. A. Gasparov, G. Tsydynzhapov, I. E. Batov +1
We have studied the temperature dependencies of the complex sheet conductance of 1-3 unit cell (UC) thick YBa2Cu3O7-x films sandwiched between semiconducting Pr0.6Y0.4Ba2Cu3O7-x la…
Suppression of 2D superconductivity by the magnetic field: quantum corrections vs superconductor-insulator transition
V. F. Gantmakher, S. N. Ermolov, G. E. Tsydynzhapov +2
Magnetotransport of superconducting Nd_{2-x}Ce_xCuO_{4+y} (NdCeCuO) films is studied in the temperature interval 0.3-30 K. The microscopic theory of the quantum corrections to cond…
Temperature Dependence of Upper Critical Field as an Indicator of Boson Effects in Superconductivity in NdCeCuO
V. F. Gantmakher, G. A. Emelchenko, I. G. Naumenko +1
The temperature dependence of upper critical field B_c2 was determined from the shift of resistive transition ΔT(B) in nearly optimally doped Nd_{2-x}Ce_xCuO_{4-y} single crystals.…
Observation of the parallel-magnetic-field-induced superconductor-insulator transition in thin amorphous InO films
V. F. Gantmakher, M. V. Golubkov, V. T. Dolgopolov +2
We study the response of a thin superconducting amorphous InO film with variable oxygen content to a parallel magnetic field. A field-induced superconductor-insulator transition (S…
