Magnetoresistance AND ROLE of CONTACTs IN ELECTRICAL Conductivity of compacted Nanodispersed Carbon Materials
Structures obtained by compaction of nano- and microcarbon materials, carbon nano and microparticles in the amorphous state, carbon nanofibers and destructed graphite has been studied. The analysis of the results obtained in the study of the magnetoresistance showed that hopping conduction mechanism between localized states near the Fermi level with a variable range hopping and jumping between neighboring localized states is dominated in the samples. It is concluded that the hopping conductivity is mainly due to the properties of contacts between particles
