Abstract
In this work we present DC-magnetization measurements on superconducti ng Rb3C60 compounds. Special emphasis was put on the preparation to mi nimize structural defects within the samples. Magnetization measuremen ts showed no indication of a granular structure. We discuss the diffic ulties in determining the lower critical field B-cl that even occur in these highly crystalline samples. The experimental results possibly c ould be explained by the existence of a B-cl(0)-value lower than 5 G. The results are also discussed with respect to granular behavior.
