“…makes it possible to divide the susceptibility into two components: the temperatureindependent part χ P and the part obeying the Curie law χ = C/T (see, e.g., data for polyaniline (Wang et al, 1992;Ranghunathan et al, 1999;Kahol et al, 2005a), polythiophene (Kahol et al, 2005a), and polypyrrole (Joo et al, 2001). The origin of these two components is usually explained within the framework of the "metallic" model, which treats doped conducting polymers (in the form of both powders and films) as highly ordered metallic domains immersed into amorphous domains.…”
