Electrical conductivity and magneto-resistance studies on polyaniline-PMMA blends at very low temperature
- 51 Downloads
D.C. electrical conductivity of polyaniline(33%,40%) blended with PMMA was measured from 5K to 300mK. The conductivity behaviour is consistent with fluctuation induced tunneling. Magneto-resistance (MR) was measured between 300K and 2K. From 20K to 2K, a large positive MR was observed. At 2K, for low magnetic fields (<1 Tesla), a deviation from the normal H2 behaviour was observed.
