Experimental progress is reviewed with emphasis on magnetic and transport studies. The magnetic results are fully consistent with the soliton doping mechanism; the decrease in Curie-law contribution has been demonstrated; the Pauli term remains small (Y < 0.07) and is apparently zero in the limit of completely uniform doping. The electrical conductivity (P and T dependence) and thermopower (n-type and p-type) are in excellent agreement with Kivelson's theory of intersoliton electron hopping.
Heeger et al. (1981) studied this question.
