Long-range effects in superconductor-ferromagnet structures

F. S. Bergeret, A. F. Volkov, K. B. Efetov

We analyze the proximity effect in a superconductor/ferromagnet (S/F) structure with a local inhomogeneity of the magnetization in the ferromagnet near the S/F interface. We demons…

Josephson effects in a superconductor-normal metal mesoscopic structure with a dangling superconducting arm

R. Shaikhaidarov, A. F. Volkov, H. Takayanagi +2

We studied a mesoscopic cross-like normal metal structure connected to two superconducting (S) and two normal (N) reservoirs. We observed the Josephson effect under unusual conditi…

Pressure Dependence of the Barrier Height in Tunnel n-GaAs/Au Junctions

E. M. Dizhur, A. N. Voronovsky, A. Ya. Shul'man +1

The theory of tunnel current-voltage (I-V) characteristics of metal-semiconductor junctions based on the self-consistent solution of Poisson equation allows to get the Schottky-bar…

Superconducting current-phase relation in Nb/Au/(001)YBa2Cu3Ox heterojunctions

P. V. Komissinski, E. Il'ichev, G. A. Ovsyannikov +6

We probe directly the superconducting current-phase relations (CPR) of Nb/Au/(001) YBa2Cu3Ox heterojunctions prepared in epitaxial c-axis oriented YBa2Cu3Ox (YBCO) thin films. The…

Semiclassical theory of shot noise in disordered SN contacts

K. E. Nagaev, M. Buttiker

We present a semiclassical theory of shot noise in diffusive superconductor - normal metal contacts. At subgap voltages, we reproduce the doubling of shot noise with respect to con…

On Effect of Equilibrium Fluctuations on Superfluid Density in Layered Superconductors

S. N. Artemenko, S. V. Remizov

We calculate suppression of inter- and intralayer superconducting currents due to equilibrium phase fluctuations and find that, in contrast to a recent prediction, the effect of th…

Giant thermoemf in multiterminal superconductor/normal metal mesoscopic structures

R. Seviour, A. F. Volkov

We considered a mesoscopic superconductor/normal metal (S/N) structure in which the N reservoirs are maintained at different temperatures. It is shown that in the absence of curren…

Current driven switching of magnetic layers

C. Heide, P. E. Zilberman, R. J. Elliott

The switching of magnetic layers is studied under the action of a spin current in a ferromagnetic metal/non-magnetic metal/ferromagnetic metal spin valve. We find that the main con…

Contributions of spontaneous phase slippage to linear and non-linear conduction near the Peierls transition in thin samples of o-TaS_3

V. Ya. Pokrovskii, S. V. Zaitsev-Zotov

In the Peierls state very thin samples of TaS_3 (cross-section area \sim 10^{-3} mkm^2) are found to demonstrate smearing of the I-V curves near the threshold field. With approachi…

Nonlinear electron transport in normally pinched-off quantum wire

K. S. Novoselov, Yu. V. Dubrovskii, V. A. Sablikov +6

Nonlinear electron transport in normally pinched-off quantum wires was studied. The wires were fabricated from AlGaAs/GaAs heterostructures with high-mobility two-dimensional elect…

Phase-coherent effects in multiterminal superconductor/normal metal mesoscopic structures

A. F. Volkov, R. Seviour

In this report we analyse three effects which may arise in a mesoscopic multiterminal S/N structure (two normal and two superconducting reservoirs). We show that the Josephson crit…

Suppression and enhancement of the critical current in multiterminal S/N/S mesoscopic structures

R. Seviour, A. F. Volkov

We analyse the measured critical current in a mesoscopic 4-terminal S/N/S structure. The current through the S/N interface is shown to consist not only of the Joseph…

Dielectric response of charge induced correlated state in the quasi-one-dimensional conductor (TMTTF)2PF6

F. Nad, P. Monceau, C. Carcel +1

Conductivity and permittivity of the quasi-one-dimensionsional organic transfer salt (TMTTF)2PF6 have been measured at low frequencies (10^3-10^7 Hz) between room temperature down…
