Abstract

The Schumacher-Slichter technique was utilized to determine the absolute Pauli spin susceptibility of stage-1 and stage-2 graphite-As $F_{5}$ intercalation compounds. The results lead to a determination of the densities of states at the Fermi energy, 2.8× $10^{21}$ and 3.7× $10^{21}$ states/eV ${cm}^{3}$ , respectively; substantially lower than in metals with comparable conductivity.
