摘要：

We have investigated the complete electrodynamic response of the newly discovered alkali fulleride linear polymers A(1)C(60). We find clear evidence for a metal-insulator phase transition at low temperatures in Rb1C60 and Cs1C60, while the K compound remains metallic at all temperatures. The possibility of a broken symmetry ground state due to the formation of a spin density wave for the Rb and Cs compounds, as suggested by the magnetic properties, is discussed.
