Abstract

The electrical resistivity of single-crystal Rb₃C₆₀ has been measured in magnetic fields up to 7.0 T. A substantial broadening of the resistive transition to the superconducting state is observed and attributed to the combined effects of magnetofluctuations near T_c and thermally activated flux creep dominant at lower temperatures. We evaluate characteristic parameters for Rb₃C₆₀ crystals including the upper critical field H_c2(T), the scattering time τ, coherence length ξ, and mean free path l; these are contrasted to similar parameters determined previously for K₃C₆₀.
