Abstract

Dielectric properties of composite materials made of epoxy resin filled with different concentrations of goethite (Fe₂O $_{3} \cdot$ H₂O) nanorods and manganese ferrite (MnFe₂O₄) are presented in a wide frequency range. The electrical percolation threshold in these composites is close to 30vol.%. Electrical conductivity in the composites occurs both below and above the percolation threshold due to the finite conductivity of the epoxy resin under high temperatures.
