In this brief review, I consider a rather mundane property of MgB 2, namely its resistivity as a
function of temperature. It turns out that a comparison of resistivity data for a wide variety of …

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 …

The recently discovered Fe-pnictide and chalcogenide superconductors display low-
temperature properties suggesting superconducting gap structures which appear to vary …

In the present paper we report the effect of graphene oxide (GO) do** on the structural
and superconducting properties of MgB 2. Bulk polycrystalline samples have been …

Quasiclassic Usadel equations for two-band superconductors in the dirty limit are derived
with the account of both intraband and interband scattering by nonmagnetic impurities. From …

We demonstrate the existence of a novel superconducting state in high quality two-
component MgB 2 single crystalline superconductors where a unique combination of both …

The low temperature behaviour of the magnetic penetration depth λ (T) provides a useful
probe of the low lying excitations in superconductors and hence of the anisotropy of the …

We review the current situation in the theory of superconducting and transport properties of
MgB2. First principle calculations of the electronic structure and electron–phonon coupling …

We report a significant enhancement of the upper critical field H c2 of different MgB 2
samples alloyed with nonmagnetic impurities. By studying films and bulk polycrystals with …

This review focuses on the most important features of the 40 K superconductor MgB 2—the
weakly interacting multiple bands (the σ and π bands) and the distinct multiple …
