This paper reports that the penetration depth {lambda} and the coherence length {xi} in Rb{sub 3}C{sub 60} fullerene are determined by means of magnetic measurements n fields up to 50 kOe. For the Ginzburg-Landau coherence length the estimate {xi}{sub GL}(0) = 23 {Angstrom} is obtained, while the magnitude of {lambda}{sub GL}(0) extracted from the high-field data turns out to lie between 1200 and 1400 {Angstrom}, with the upper value being more likely. Non-superconducting diamagnetic susceptibility is also measured and found to be equal to {minus}(0.60 {plus minus} 0.02) {times} 10{sup {minus}5} which is an order of magnitude higher than that of undoped fullerene.
