Abstract

A new material of higher fullerene, RbxC84, was synthesized by intercalating Rb metal into C84 crystals. The RbxC84 crystals showed a simple cubic (sc) structure with lattice constant, a, of 16.82(2)Å at 6.5K, and 16.87(2)Å at 295K. The Rietveld refinements were achieved with the space group, Pa3̄, based on a model that the C2 axis of D2d-C84 aligned along [111]. The sample composition was determined to be Rb8.8(7)C84. The ESR spectrum at 303K was composed of a broad peak with peak-to-peak linewidth ΔHpp of 220G, and a narrow peak with ΔHpp of 24G. Temperature dependence of the broad peak clearly showed a metallic behavior. The metallic behavior was discussed based on a theoretical calculation. This finding of new metallic phase in a higher fullerene is the first step for a development of new types of fullerene materials with novel physical properties such as superconductivity.
