Abstract

The superconducting properties of MgB1.96C0.04 have been investigated by the transverse-field muon spin rotation (TF-μSR) technique. The extracted temperature dependence of the μ+ spin depolarization rate, σ at TF = 0.6T has been analyzed in terms of a two-gap model. Carbon doping affects the size of both superconducting gaps and the doping effect is more pronounced for the smaller gap, which is related to the 3D π-sheets of the Fermi surface. The 'universal' correlation between the superconducting transition temperature, Tc and the effective Fermi temperature, TF (Uemura plot) is also discussed.
