摘要：

A strongly temperature dependent paramagnetic hyperfine contact NMR shift which saturates below T(c) has been observed for the methyl group protons in tetrakis-dimethylamino-ethylene (TDAE+)-C60. The magnitude of the shift below T(c) is much smaller than expected if all C60 unpaired spins would order ferromagnetically. The results confirm the existence of a magnetic transition in TDAE-C60 and suggest that ferromagnetically correlated clusters appear below T(c) in a sea of spin cancelled regions.
