Sažetak
We report on the measurements of the C-13 NMR line shape in the organic ferromagnet tetrakis(dimethylamine) ethylene-C-60 between room temperature and 4 K as well as on a simulation of the line shape in this interval. It is shown that the sudden increase in the inhomogeneous C-13 NMR linewidth in the middle of the ferromagnetic phase can be explained by the freezeout of the pseudorotations of the axes of the Jahn-Teller distortions of the C- 60(-) ions. The correlation times for the Jahn- Teller dynamics of the C-60(-) ions have been extracted from a comparison of experimental and simulated C-13 NMR line shapes. A strong correlation between spin ordering and orbital ordering has been found.
