This paper presents an overview of the current state of the art in research into the electronic structure and properties of a new superconductor, namely, MgB2, and a large number of related compounds by computational methods of the band theory. Consideration is given to the specific features of the surface states of magnesium diboride, the electron and hole doping effects in this compound, and the concentration dependences of the band structure and the properties of Mg1−xMexB2 and MgB2−yXy…

Loss of superconductivity with the addition of Al to MgB2 and a structural transition in Mg1-x AlxB2
TLDR
It is shown that the addition of electrons to MgB2, through partial substitution of Al for Mg, results in the loss of superconductivity, reflected in the partial collapse of the spacing between boron layers near an Al content of 10 per cent.

TLDR
The results clearly show the importance of B p-band for superconductivity and show that around E(F), the charge density in MgB, BeB, and NaB (2) is planar and is associated with the B plane.

Superconductivity in the non-oxide perovskite MgCNi3
TLDR
The high relative proportion of Ni in MgCNi3 suggests that magnetic interactions are important, and the lower Tc of this three-dimensional compound—when compared to the LnNi2B2C family—contrasts with conventional ideas regarding the origins of superconductivity.
