Abstract
Superconducting phase in conducting polymer - C-60 composites weakly doped by alkali metal is revealed by low-field microwave absorption (LFMA). ESR a nd LFMA intensities increase with light irradiation. The increase of LFMA i ntensity can be derived from the change of electronic charge distribution i n alkali metal doped CP-C-60 composites with coexistence of mobile charges in CP chains pi - electron network and highly charged C-60(n-) anions upon photopumping.
