The discovery of high-temperature superconductivity in copper oxides was not accidental,
but was based on the knowledge that the divalent copper ion, Cu2+, is one of the strongest …

In tunneling spectroscopy studies of ferromagnet/superconductor (F/S) junctions, the effects
of spin polarization, Fermi wave-vector mismatch (FWM) between the F and S regions, and …

We analyze the frequency-dependent photoinduced infrared conductivity, σ P (ω), obtained
from photoinduced absorption measurements of the insulators Tl 2 Ba 2 Ca 0.98 Gd 0.02 Cu …

The recent discovery of high-temperature superconductivity has resulted in a remarkable
growth in the amount of research and the number of researchers working in this exciting …

The results of first-principles calculations of the electronic structure and the electron-phonon
interaction in MgB 2 are used to study theoretically the temperature dependence and …

An induced superconducting state caused by charge transfer between intrinsically
superconducting (α) and intrinsically normal (β) subsystems is studied. A most interesting …

A distinctive feature of layered conductors is the presence of low-energy electronic collective
modes of the conduction electrons. This affects the dynamic screening properties of the …

We investigate the vortex state in a two-band superconductor with strong intraband and
weak interband electronic scattering rates. Coupled Usadel equations are solved …

We report experimental data showing the Feshbach shape resonance in the electron doped
MgB 2 where the chemical potential is tuned by Al, Sc, and C substitutions. The scaling of …

The very high superconducting transition temperatures T c of cuprates are not yet
substantiated in applications which seem intimately related to the layered nature of the …
