Superconducting properties of metallic nanowires can be entirely different from those of bulk
superconductors because of the dominating role played by thermal and quantum …

We present detailed measurements of the longitudinal resistivity ρ xx (T, H) and the upper
critical field H c 2 of NdFeAsO 0.7 F 0.3 single crystals in strong dc and pulsed magnetic …

THE superconducting state of a material can be suppressed by either increasing the
temperature (T) or applying a magnetic field (H). For bulk samples, the form of the H–T …

The interaction between superconductivity and ferromagnetism, which entails incompatible
spin order, is one of the problems of fundamental interest in condensed-matter physics. In …

The emergence of superconductivity in doped insulators such as cuprates and pnictides
coincides with their doping‐driven insulator–metal transitions. Above the critical doping …

An anomalous superconducting transition consisting of a very sharp peak in the resistance
versus temperature curve just above T c has been observed in (NbV) N films and other …

Anomalous resistance oscillations have been observed in meso-scopic superconducting Al
loops. As for the classical Little-Parks effect, the oscillation period is governed by the …

We develop a general framework for describing thermoelectric effects in phase-coherent
superconducting structures. Formulas for the electrical conductance, thermal conductance …

The abrupt drop of resistance to zero at a critical temperature is a key signature of the
current paradigm of the metal–superconductor transition. However, the emergence of an …

In a variety of superconductors, mostly in two-dimensional (2D) and one-dimensional (1D)
systems, the resistive superconducting transition R (T) demonstrates in many cases an …
