Abstract

Muon spin relaxation has been measured in longitudinal and zero field
configurations for a number of conducting polymers in the polypyrrole
and polyaniline families. The measurements have been made as a function
of temperature down to 11K and in applied fields up to 2000G. Hyperfine
parameters have been deduced for the coupling between muon and polaron
spins and the spin dynamics has been modeled on the basis of polaron
diffusion, which has one-dimensional character at low temperatures,
becoming more two-dimensional at room temperature.
