摘要：
The conduction electron spin resonance (CESR) of Rb3C60 has been observed for the first time and the spin susceptibility found to be chi(s) = (12.4 +/- 4) x 10(-4) emu/mol, in agreement with static measurements. The CESR linewidth is anomalously large, 1300 G at 30 K giving a spin lattice relaxation rate T(l)-1 = 9.0 x 10(-11) sec-1, and we suggest that it is caused by large molecular disorder. The ESR line formerly assigned to Rb3C60 arises from an unidentified nonsuperconducting phase RbxC60 which has a structural transition near 400 K and a thermal history dependent metal-insulator transition at lower temperatures.
