Abstract
Conductivity (sigma) vs temperature and magnetoresistance (MR) were measure d in CSA-doped-polyaniline films aged for different times. sigma is well ac counted for in an heterogeneous picture of metallic islands separated by re gions in which transport is of hopping type. MR gives evidence for a spin-a lignment transport mechanism in these regions.
