Abstract
Polyaniline doped with camphor sulfonic acid (PANI-CSA) has been shown to yield a material which, after processing from solutions in meta-cr esol, exhibit a temperature independent magnetic susceptibility down t o 50K. Below 50K a Curie like contribution sets in. We also report C-1 3 NMR experiments which clearly show that the C-13 spin lattice relaxa tion rates obey the Korringa relation for relaxation via the hyperfine coupling to conduction electrons.
