Zusammenfassung
The superconducting properties of Ag1-xMo6S8 [x = 0.08(1)] Chevrel phase [T-c = 7.9(5) K] are studied on a sample compacted by spark plasma sintering. Both lower (B-c1 = 12(1) mT) and the upper [B-c2(0) approximate to 7.4(9) T] critical magnetic fields are obtained from magnetization and electrical resistivity measurements for the first time. The analysis of the low-temperature electronic specific heat indicates Ag1-xMo6S8 to be a two band superconductor with the energy gaps Delta(1) = 1.6 meV (95%) and Delta(2) = 0.7 meV (5%). Theoretical DFT calculations reveal a much stronger electron-phonon coupling in the studied Chevrel phase compared to earlier reports. Similar to MgB2, the Fermi surface of studied Chevrel phase is formed by two hole-like and one electron-like bands.
