摘要：

The properties of the mixed state of a Rb3C60 fullerene superconductor are investigated. The magnetic field dependence of the critical current density (J(c)) from the hysteretic magnetization curves is calculated. Two regimes in the field dependences are found. An explanation of the experimental results is given in terms of a transition between short-range and long-range vortex structures. This transition occurs at a characteristic magnetic field H. From the hysteretic magnetization curves the values of the irreversibility magnetic fields at different temperatures are obtained.
