Abstract

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.
