Abstract
We report Hall resistance measurements of the organic conductor (TMTSF)
2ClO
4 at low temperatures in fields up to 12 T. We have found that the Landau filling factor of the very stable semimetallic phase
above 8 T is very likely to be
n=1 instead of
n=1/3 as inferred from previous investigations. A comparison between different samples shows that the possible current non-uniformity
can strongly affect the experimental magnitude of the Hall resistance and thus leads to a wrong determination of the Landau
filling factor.
