Abstract
The ESR line width of the C60 − anion in samples of fullerides (Na, K, Zn, and In) with low metal content (0.01%) is ∼0.1 mT at 77 K and ∼1 mT at 300 K. The line shape is fitted better by the Lorentzian function than by the Gaussian function. The spin-lattice relaxation likely makes some contribution to the line width. Time-dependent changes in the ESR spectra were observed: they are related to diffusion of cations to defects of the crystalline lattice.
