Structural influence on the intensitiy ratio of the T' and T Rb-87 NMR lines and the superconductivity in Rb3C60
The intensity ratio of the T'/T Rb-87 NMR lines in Rb3C60 could be changed by different cooling rates after annealing at 380 degrees C. The results are discussed with respect to magnetically different surroundings of the Rb ions through the two standard orientations of the C(60)(3-)ions. Additionally, the superconducting volume fraction is influenced by the different cooling procedures.
