The superconducting state of Ca-intercalated graphite CaC6 has beeninvestigated by specific heat measurements. The characteristic anomaly at thesuperconducting transition (Tc = 11.4 K) indicates clearly the bulk nature ofthe superconductivity. The temperature and magnetic field dependence of theelectronic specific heat are consistent with a fully-gapped superconductingorder parameter. The estimated electron-phonon coupling constant is lambda =0.60 - 0.74 suggesting that the relatively high Tc of CaC6 can be explainedwithin the weak-coupling BCS approach.Comment: 4 pages, 4 figs, submitted to Phys.
