Abstract

Rb K-edge XAFS of Rb6C60 and Ba K-edge XAFS of Ba6C60 and K3Ba3C60 have been studied, all of which take a bcc structure. The radial structure functions obtained by Fourier transform of XAFS spectra for these compounds showed two pronounced envelopes which can be attributed to the scattering between metal ion and the neighboring C atoms and that between metal ions. The mean-square-displacements for the metal-C in these compounds were larger than that for the t-site Rb-C in Rb3C60 because of the distribution in metal-C distances. From the temperature dependent XAFS, it has been found that the mean-square-displacement for Rb-C in a non-superconductor Rb6C60 shows no anomaly around superconducting transition temperature, contrary to a superconductor Rb3C60.
