Abstract
The electrical resistivity of single-crystal Rb3C60 has been measured in magnetic fields up to 7.0 T. A substantial broadening of the resist ive transition to the superconducting state is observed and attributed to the combined effects of magnetofluctuations near T(c) and thermall y activated flux creep dominant at lower temperatures. We evaluate cha racteristic parameters for Rb3C60 crystals including the upper critica l field H(c2)(T), the scattering time tau, coherence length xi, and me an free path l; these are contrasted to similar parameters determined previously for K3C60.
