The different development of the anisotropic upper critical field in MgB2 by aluminum and carbon doping
M. Angst, S. L. Bud'ko, R. H. T. Wilke +1
The temperature dependence of the upper critical field, Hc2, for both field directions in partially substituted polycrystalline MgB2 was determined. Whereas the suppression of Tc i…

Systematic study of the two band/two gap superconductivity in carbon-substituted MgB2 by point-contact spectroscopy
Z. Holanova, P. Szabo, P. Samuely +3
Point-contact measurements on the carbon-substituted Mg(BC) filament/powder samples directly reveal a retention of the two superconducting energy gaps in the whole…
