Query: 1D to 3D Dimensional Crossover in the Superconducting Transition of the
  Quasi-One-Dimensional Carbide Superconductor Sc3CoC4   The transition metal carbide superconductor Sc3CoC4 may represent a new
benchmark system of quasi-1D superconducting behavior. We investigate the
superconducting transition of a high-quality single crystalline sample by
electrical transport experiments. Our data show that the superconductor goes
through a complex dimensional crossover below the onset Tc of 4.5 K. First, a
quasi-1D fluctuating superconducting state with finite resistance forms in the
CoC4 ribbons which are embedded in a Sc matrix in this material. At lower
temperature, the transversal Josephson or proximity coupling of neighboring
ribbons establishes a 3D bulk superconducting state. This dimensional crossover
is very similar to Tl2Mo6Se6, which for a long time has been regarded as the
most appropriate model system of a quasi-1D superconductor. Sc3CoC4 appears to
be even more in the 1D limit than Tl2Mo6Se6.
