中文摘要	We have observed a small and temperature insensitive thermal electric power S as well as a large resistivity following rho similar to-log(T) dependence, in percolating magnetic metal-insulator nanocomposites, irrespective to the sign of the carrier. Upon annealing, however, a normal metallic behavior with a linear temperature dependence for both S and rho was recovered. We propose that the large charging energy of the nanometer sized particles in the percolation conduction channels is responsible for this observation as well as the giant Hall effect or the loss of the effective carrier density in these nanostructures.
