摘要
The intensity ratio of the T′/T87Rb NMR lines Rb3C60 could be changed by different cooling rates after annealing at 380°C. The results are discussed with respect to magnetically different surroundings of the Rb ions through the two standard orientations of the C603-ions. Additionally, the superconducting volume fraction is influenced by the different cooling procedures.
