The influence of a small change of carrier number on the superconducting transition temperature Tc in the incommensurate organic superconductors is investigated for MDT-TSF I3 0.422 MDT-TSF: methylenedithiotetraselenafulvalene, Tc=4.9 K in comparison with MDT-TSF AuI2 0.436 Tc=4.5 K . Careful estimation of the degree of charge transfer by means of the Raman spectra as well as the Shubnikov–de H...

Macroscopic mechanisms of applied current penetration in high-Tc superconductors are discussed to understand the basic physical trends, which are characteristic for the stable and unstable formation of the thermo-electrodynamics states of high-Tc superconductors placed in DC external magnetic field. The performed analysis shows that the definition of the current stability conditions of high-Tc ...

– We consider ferromagnetic particles embedded into a superconductor and study the screening of their magnetic moments by the spins of the Cooper pairs in the superconductor. It is shown that a magnetic moment opposite to the one of the ferromagnetic particle is induced in the superconductor. In the case of a small itinerant ferromagnet grain and low temperatures the full screening of the magne...

I A general two-dimensional analytical solution is presented for the / problem of transport current injection from a normal conductor into a I 1 superconductor and collection back into a normal conductor. The current distribution is solved for the general case which takes in the full range from essentially point source to full-width injection and collection. The current distribution also repres...

An Analog-to-Digital Converter (ADC) is a mixed-signal electronic circuit that converts an electrical signal from the analog domain to the digital domain, typically providing N binary bits at the sampling frequency f s. The higher speed of superconducting circuits comparable to conventional circuits provided an initial interest in superconductor technology for ADC applications. One can find tec...

– The study of the anion ordered (TMTSF )2ClO4(1−x)ReO4x solid solution in the limit of a low ReO− 4 substitution level (0 ≤ x ≤ 17%) has revealed a new and interesting phase diagram. Superconductivity is drastically suppressed as the effect of ReO− 4 non magnetic point defects increases following the digamma behaviour for usual superconductors in the presence of paramagnetic impurities. Then, ...

We report the observation of periodic-orbit resonance POR in a metal possessing pure quasi-onedimensional Q1D Fermiology—namely, the organic linear-chain compound TMTSF 2ClO4, whose Fermi surface consists of a pair of weakly warped sheets. The POR phenomenon is related to weak interchain coupling, which allows electrons constrained on open trajectories to acquire small transverse velocities. Th...

Quasiclassical Green's functions of a short superconductor/normal metal/superconductor (SNS) junction are calculated for multi-mode junction with arbitrary electron transmission properties. They provide the basis for description of all of the junction transport characteristics , and are used to calculate the equilibrium spectral density of supercurrent fluctuations.

We calculate the tunneling conductance spectra of a normalmetal/insulator/triplet superconductor using the Blonder-Tinkham-Klapwijk (BTK) formulation. Possible states for the superconductor are considered with horizontal lines of nodes, breaking the time reversal symmetry. These results would be useful to discriminate between pairing states in superonductor Sr2RuO4 and also in UPt3. 74.20. z, 7...
