Description

We report normal-state and superconducting properties of the clathrate-type silver-oxide Ag6O8AgHF2. We present electrical resistivity, DC- and AC-susceptibility and specific-heat measurements of single crystalline Ag6O8AgHF2. In the normal state, Ag6O8AgHF2 exhibits metallic conductivity and a phase transition near 110 K, possibly a structural phase transition as observed in the related compound Ag6O8AgNO3. The onset of superconductivity of our samples is observed around 1.2-1.5 K, and the H-T phase diagram is determined for the first time. The upper critical field Hc2(0) is estimated to be about 2000-2200 Oe and the coherence length ξGL(0) to be 40 nm
