Magnetic Spin Susceptibility of AsF5-Intercalated Graphite: Determination of the Density of States at the Fermi Energy

Abstract
The Schumacher-Slichter technique was utilized to determine the absolute Pauli spin susceptibility of stage-1 and stage-2 graphite-AsF5 intercalation compounds. The results lead to a determination of the densities of states at the Fermi energy, 2.8×1021 and 3.7×1021 states/eV cm3, respectively; substantially lower than in metals with comparable conductivity.
