Abstract
A strongly temperature dependent paramagnetic hyperfine contact NMR sh ift 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 unpai red spins would order ferromagnetically. The results confirm the exist ence of a magnetic transition in TDAE-C60 and suggest that ferromagnet ically correlated clusters appear below T(c) in a sea of spin cancelle d regions.
