Abstract
- The paper presents the results from studies of the electrical and magnetic properties of an inhomogeneous percolated medium based on the theory of percolation. The application of this theory has a wide and varied range. Examples include hopping conductivity in semiconductors, properties of porous materials, etc. It was found that, with approaching the percolation threshold p<subscript>c</subscript> = 0.35, the resistivity decreases, and the electrical conductivity increases accordingly. An increasing number of individual ferromagnetic nanogranules in (p)–Fe<subscript>2</subscript>O<subscript>3</subscript>–(1–p) (MBT) composites merge with the formation of individual Fe<subscript>2</subscript>O<subscript>3</subscript> clusters in the bentonite matrix, which combine to form a continuous network of clusters. This is due to the fact that the resistivity ρ of the composite is mainly determined by the magnetic component of the latter. [ABSTRACT FROM AUTHOR]
