摘要：

The positive magnetoresistance of disordered fully-FeCl3-doped polyacetylene showed a pronounced maximum near 2 T below 4.2 K. This contrasts with the magnetoresistance for disordered I2-doped sample showing a dull maximum. The results are analyzed in terms of the magnetic field effect to the hopping conduction among Anderson-localized states with Coulomb correlation. The difference by the dopant species is ascribed to the depth of the Fermi level from the mobility edge.
