Paramagnetism and specific heat of the graphite lamellar compound C6Li

Abstract
The alkali-metal graphite lamellar compounds C8M with M = K, Rb, Cs are well known. In the first stage intercalation compounds the occurence of superconductivity, below 1 K, has been reported [1] and discussed [2] but not confirmed [3]. A lamellar compound with lithium was studied a long time ago [4] but only recently was it synthesized with a well-defined stoichiometry (C6Li) [5]. In order to understand the electronic structure of this metallic compound and to examine the possible existence of superconductivity the physical properties at thermal equilibrium, namely static susceptibility, E.P.R., and specific heat have been examined at temperatures down to 1.5 K
