Many of the fundamental questions regarding the solid‐state chemistry of boron are still
unsolved, more than 200 years after its discovery. Recently, theoretical work on the …

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 upper critical field, H c 2, of Mg (B 1-x C x) 2 has been measured in order to probe the
maximum magnetic field range for superconductivity that can be attained by C doping …

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 …

Magnesium boride, MgB 2, has attracted much attention since the discovery of its
superconductivity in 2001. The absence of weak-links in grain boundaries, less prominent …

We investigated the effect of alloying on the upper critical field H c 2 for 12 Mg B 2 films, in
which disorder was introduced by growth, carbon doping or He-ion irradiation, finding a …

The effect of carbohydrate doping on lattice parameters, microstructure, T c⁠, J c⁠, H irr⁠,
and H c 2 of Mg B 2 has been studied. In this work the authors used malic acid as an …

The growth of carbon-substituted magnesium diboride Mg (B 1− x C x) 2 single crystals with
0⩽ x⩽ 0.15 is reported, and the structural, transport, and magnetization data are presented …

An overview of the theory of the upper critical field in dirty two-gap superconductors, with a
particular emphasis on MgB2 is given. We focus here on the maximum Hc2 which may be …

We argue, based on band structure calculations and the Eliashberg theory, that the
observed decrease of T c of Al and C doped M g B 2 samples can be understood mainly in …
