Abstract
D.C. electrical conductivity of polyaniline (33%,40%) blended with PMM A was measured from 5K to 300mK. The conductivity behaviour is consist ent with fluctuation induced tunneling. Magneto-resistance (MR) was me asured between 300K and 2K. From 20K to 2K, a large positive MR was ob served. At 2K, for low magnetic fields (<1 Tesla), a deviation from th e normal H-2 behaviour was observed.
