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 Tc and thermally activated flux creep dominant at lower temperatures. We evaluate characteristic parameters for Rb3C60 crystals including the upper critical field Hc2(T), the scattering time τ, coherence length ξ, and mean free path l; these are contrasted to similar parameters determined previously for K3C60.
