Abstract

The polymer�amorphous carbon composites show a negative magnetoconductance which varies as $B^2$ at low fields which changes to $B^{\frac{1}{2}}$ at sufficiently high fields. The magnetoconductance gives the evidence of electron�electron interaction in composites whose conductivity follows thermal fluctuation induced tunneling and falls in the critical regime.
