摘要：

Conductivity (sigma) vs temperature and magnetoresistance (MR) were measured in CSA-doped-polyaniline films aged for different times. sigma is well accounted for in an heterogeneous picture of metallic islands separated by regions in which transport is of hopping type. MR gives evidence for a spin-alignment transport mechanism in these regions.
