ELECTRIC PROPERTIES OF SYNTHETIC NANOSTRUCTURES: XVII International Winterschool/Euroconference on Electronic Properties of Novel Materials | 2004

The molecular structure of La2@C80 was investigated theoretically and experimentally. The most stable configuration was found to be D3d symmetry. La ions can move between ten equivalent D3d configurations via D2h configuration. The resulting dodecahedral trajectory of La ions agrees well with an X‐ray powder diffraction experiment.

Physical properties of bco phase of Cs3+αC60 (α=0.0−1.0) and A15 phase of Cs3C60 are studied by X-ray diffraction, ESR, AC susceptibility, resistivity and Raman. The ESR of Cs300(6)C60 showed a broad peak of ∼380 G due to conduction electron, while no broad peak was observed in the ESR of bco Cs3+αC60 (α≠0.0) and A15 phase. This shows that only bco phase of Cs3C60 is metallic. The AC susceptibility of bco phase of Cs3.2(3)C60 and Cs3.5(1)C60 showed no superconducting transition above 1.3 K even under high pressure, and the resistivity was 0.52 Ω cm for both samples.
