The in-plane longitudinal resistivities (Formula presented) and (Formula presented) of a single-crystal of (Formula presented) have been measured as a function of magnetic field (Formula presented) (less than 6.75 T) and temperature (Formula presented) near (Formula presented) We found that the (Formula presented) data in the mixed state collapse into a single curve as a function of (Formula presented)The extracted fluctuation conductivity exhibits dynamic scaling over a wide range of (Formula presented) and (Formula presented) assuming that the static universality class is the three-dimensional (Formula presented) model yields the observed dynamic critical exponent (Formula presented) apparently consistent with the dynamic universality class of superfluid (Formula presented) In zero field, the data are inconclusive, and a reliable determination of (Formula presented) is not possible. © 1997 The American Physical Society.
