In the past 5 years, various kinds of doping of MgB2, including single elements (metal and
non-metal), silicates, various carbon sources, and other compounds have been investigated …

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, MgB 2, and a large number of …

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 …

Neutron powder diffraction has been used to characterize a sample of C-substituted MgB2
synthesized from Mg and B4C (with isotopically enriched 11B). The sample is multiphase …

Carbon-substituted MgB2 single crystals, Mg (B1− xCx) 2 of 0.3–1.0 mm size were grown for
x= 0.02–0.15 by a high-pressure technique. The doping dependence of lattice constants …

The effect of doping MgB2 with carbon nanotubes on transition temperature, lattice
parameters, critical current density and flux pinning was studied for MgB2xCx with x 0, 0.05 …

A brief summary is given of the current status of chemical substitution experiments in MgB2.
Analysis of the data in the literature shows that only in a handful of cases has partial …

Polycrystalline MgB2− xCx samples with x= 0.05, 0.1, 0.2, 0.3 and 0.4 nano-particle carbon
powder were prepared using an in situ reaction method under well-controlled conditions to …

The effects on transition critical temperature, lattice parameters, critical current density, and
flux pinning of doping MgB 2 with carbon nanoparticles, were studied for bulk, wire and tape …

Single crystals of Mg 1− x Al x B 2 have been grown at a pressure of 30 kbar using the cubic
anvil technique. Precipitation free crystals with x< 0.1 were obtained as a result of the …
