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.
