Abstract

We have measured the magnetoresistance of metallic polyacetylene at temperatures T between 4.2 K and 0.3 K and in fields B up to 3.4 Tesla both parallel and perpendicular to the average current flow. We found an exclusively positive magnetoresistance scaling in low fields as B2/T2 for T < 1 K and as B2/T3 for T > 2 K. At high doping levels the magnetoresistance is small and saturates in high ...
