abstract
13C, 1H, and 39K-NMR measurements of (NH3)K3C60 unambiguously demonstrated that its magnetic properties are described as a S=1/2 localized spin system over the entire temperature range (300 K–4.2 K). A possible antiferromagnetic structure that appeared below 45 K is compatible with the orientational order of K-NH3 pairs on the octahedral (O) site. The present NMR study strongly suggests that the Mott-Hubbard localization occurs due to the removal of the C60 t1u-orbital degeneracy.
