Abstract
Superconducting phases in composites of C 60 with various types of conducting polymer (CP) doped by alkali metals are studied by LFMA and susceptibility measurements. LFMA signal drastically changes due to the metallization of CP with increasing alkali metal doping level. At large C 60 content, Paramagnetic Meissner Effect is confirmed in field cooling curve. The existence of intergranular and intragranular junctions is supported from the results of AC susceptibility measurements.
