Abstract
We report studies of spin dynamics in the conducting polymers polyanil ine and polypyrrole using both mu(+)SR and mu(-)SR techniques. These m easurements reveal characteristic held dependences and cutoff frequenc ies for the muon spin relaxation which can be related to the spin diff usion process. Clear evidence is seen for increased spin localisation at low temperatures where a crossover occurs from two or three dimensi onal spin diffusion to a one dimensional diffusion regime.
