Abstract
The properties of the mixed state of a Rb3C60 fullerene superconductor are investigated. The magnetic field dependence of the critical curre nt density (J(c)) from the hysteretic magnetization curves is calculat ed. Two regimes in the field dependences are found. An explanation of the experimental results is given in terms of a transition between sho rt-range and long-range vortex structures. This transition occurs at a characteristic magnetic field H. From the hysteretic magnetization cu rves the values of the irreversibility magnetic fields at different te mperatures are obtained.
