abstract = {We have studied carbon-doped magnesium diboride
nanoparticles using 13C and 11B NMR in the normal and
superconducting states. Measurements of the line shape
reveal the role of carbon as a flux-pinning center and,
combined with Knight shift measurements, suggest the doping
procedure favors the chemical substitution scenario. We
perform ab initio calculations on a structure with a single
carbon-boron substitution which yield results that match the
experimental data. The 13C and 11B Knight shift data are
used to extract the spin susceptibility, which indicates a
BCS pairing mechanism; however, we do not observe the
Hebel-Slichter coherence peak from 1/T1 data, which we
hypothesize is due to a pair-breaking mechanism present in
the boron planes.},
