Abstract

Pitch based carbon fibers when annealed to high temperatures and then intercalated are of potential interest for electrical conductors. They are graphitizable, low cost, and mass producible. The P100 Union Carbide fibers are one example. P100 fibers were annealed to greater than 3000 degree C and then intercalated with CuCl//2 and with bromine. The magnetoresistances in fields to 20 Tesla at various temperatures were measured in an attempt to characterize the electronic properties of these intercalated fibers. This paper reports on measurements of the simultaneously present Shubnikov-deHaas and negative magnetoresistance effects in intercalated fibers.
