AB  - The 'expanded fulleride' Cs 3 C 60 is an antiferromagnetic insulator in its normal state and becomes a molecular superconductor with T c as high as 38 K under pressure. There is mounting evidence that superconductivity is not of the conventional BCS type and electron-electron interactions are essential for its explanation. Here we present evidence for the dynamic Jahn-Teller effect as the source of the dramatic change in electronic structure occurring during the transition from the metallic to the localized state. We apply infrared spectroscopy, which can detect subtle changes in the shape of the C 3- 60 ion due to the Jahn-Teller distortion. The temperature dependence of the spectra in the insulating phase can be explained by the gradual transformation from two temperature-dependent solid-state conformers to a single one, typical and unique for Jahn-Teller systems. These results unequivocally establish the relevance of the dynamic Jahn-Teller effect to overcoming Hund's rule and forming a low-spin state, leading to a magnetic Mott-Jahn-Teller insulator. © 2012 Macmillan Publishers Limited.

AB  - High-pressure infrared transmission measurements on (Ph 4P) 2IC 60 were performed up to 9 GPa over a broad frequency range (200-20000 cm -1) to monitor the vibrational and electronic/vibronic excitations under pressure. The four fundamental T 1u modes of C60- are split into doublets already at the lowest applied pressure and harden with increasing pressure. Several cation modes and fullerene-related modes split into doublets at around 2 GPa, the most prominent one being the G 1u mode. The splitting of the vibrational modes can be attributed to the transition from the dynamic to static Jahn-Teller effect, caused by steric crowding at high pressure. Four absorption bands are observed in the NIR-visible frequency range. They are discussed in terms of transitions between LUMO electronic states in C60-, which are split because of the Jahn-Teller distortion and can be coupled with vibrational modes. Various distortions and the corresponding symmetry lowering are discussed. The observed redshift of the absorption bands indicates that the splitting of the LUMO electronic states is reduced upon pressure application. © 2012 American Physical Society.
