Abstract

The four-probe conductivity and magnetoresistance (MR) in micron-scale for the iodine-doped polyacetylene (PA) fiber network were measured. A remarkably weaker temperature dependence of resistivity compared to that of the bulk PA film was observed. The transverse MR at T = 1.5 K was negative and its relative magnitude was approximately 0.1% at H = 10 T. The slow oscillatory tendency with small amplitude was suggested in MR. The results suggest the importance of contact barriers in the nanosize PA fiber network.
