The LF dependent muon-spin depolarization rate indicates the occurrence of pronounced shift in the relative dominance of charge transport mechanism from intra-chain diffusion to inter-chain diffusion at 50K which is higher than the 25K observed previously for the regio-regular case. © 2010 Elsevier B.V.
