  • Abstract
    We report the detail transport properties of compression molded CrO2-polymer composites. The transport measurements of the composites in the temperature range of 10-300 K were modeled using a two channel conductivity model based on spin dependent tunneling and multi-step hopping. The conductance behavior of the composite is dependent on the nature of insulating barrier which changes the nature of the grain boundaries at which spin polarized tunneling takes place.
