The relaxation of magnetization M in superconducting C60Rb3 have been measured at different temperature ranges in low magnetic fields below T c to explore the flux pinning. The measurements were performed with a superconducting quantum interference magnetometer. The applied magnetic field was 300 G

β¦ Synopsis
The magnetic and superconductivity properties of rubidium-doped C60 were studied. The temperature dependence of the irreversibility line H'(T') as determined by SQUID magnetization measurements gave a power law (n ,~ 2) scaling of the reduced relative irreversibility temperature with irreversibility field. Strong ESR signals were observed, and the influence of vortex induced line-width broadening was studied. A coexistence of ESR signals and regular series of absorption lines, presumably due to Josephson Junctions, was observed.
