Abstract

Physical properties of bco phase of Cs_3+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 Cs_3+αC₆₀ (α≠ 0.0) and A15 phase. This shows that only bco phase of Cs₃C₆₀ is metallic. The AC susceptibility of bco phase of Cs_3.2(3)C₆₀ and Cs_3.5(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.
