Abstract
We present the thermodynamic properties in the clathrate-type silver- and copper-oxides Ag6O8MX and Cu6O8MX (M = cation, X = anion) compounds, having Ag6O8 (or Cu 6O8)-cage in their crystal structure. Ag6O 8MX and Cu6O8MX are crystallized in a cubic structure with a space group of Fm3̄m. We synthesized high quality samples of Ag6O8MX and Cu6O8MX and examined the electrical resistivity, magnetic susceptibility, and specific heat measurements. The superconductivity in Ag6O8AgX (X = NO3- and HF2- have an isotropic gap symmetry by means of the specific heat data. In Cu6O8MCl, the ground sata of Cu6O 8MCl compounds changed metallic to semiconducting by changing the valence state of M site ion.
