The two-band/two-gap superconductivity in aluminium and carbon doped MgB$_2$ has been addressed by the point-contact spectroscopy. Two gaps are preserved in all samples with $T_c's$ down to 22 K. The...
Critical fluctuations in the carbon-doped magnesium diboride (2004)
Hol'anova, Z., Kačmarčik, J., Szabó, P., Samuely, P., Sheikin, I., Ribeiro, R. A., ...
Carbon doping of magnesium diboride resulting in the Mg(B0.9C0.1)(2) stoichiometry leads to the superconducting transition temperature T-c = 22 K which is about 17 K less than in the pure MgB2. We...
