This review focuses on the superconducting properties of MgB 2 that are relevant for power
applications. The reversible mixed state parameters are the most important, since they …

Point-contact spectroscopy was originally developed for the determination of the electron–
phonon spectral function in normal metals. However, in the past 20 years it has become an …

Two-band superconductivity has become an important topic over the past ten years.
Extensive experimental and theoretical studies started with MgB 2 and are now focused on …

Using the Roeser–Huber equation, which was originally developed for high temperature
superconductors (HTSc)(H. Roeser et al., Acta Astronautica 62 (2008) 733), we present a …

The review considers bulk MgB2-based materials in terms of their structure,
superconducting and mechanical properties. Superconducting transition temperatures of …

Superconductivity above 25K, and possibly above 40K, has recently been discovered in
LaO1− xFxFeAs and related compounds. We propose that this is another example of the …

The theory of hole superconductivity proposes that there is a single mechanism of
superconductivity that applies to all superconducting materials. This paper discusses …

Electronic specific heat C as a function of temperature T was calculated for a mesoscopically
disordered s-wave superconductor treated as a spatial ensemble of domains with …

An explicit expression for the temperature dependence of the specific heat of clean
anisotropic-gap superconductors is derived within the weak-coupling BCS approximation …

Based on weak-coupling anisotropic BCS theory, the temperature dependence of energy
gap and the specific heat are evaluated for the Mg B 2 superconductor, and the results are …
