Magneto-transport properties of compression molded CrO2-polymer composite
Abstract
We report detailed electrical and magnetotransport properties of compression molded CrO2-Polyimide polymer composites. The electrical transport data of the composites in the temperature range of 15-300 K were analyzed using a two-channel conductivity model based on spin dependent tunneling and multi-step hopping. The low temperature conductance is essentially dominated by spin dependent tunneling. The contribution from the multi-hopping conductivity increases with temperature increase. The presence of significant magnetoresistance in this composite is attributed partially to the opening of new conduction channels at the CrO2-polymer interface. © SAGE Publications 2007.
