The temperature and field dependence of the muon spin relaxation rate and Knight shift clearly evidence type II bulk superconductivity below $T\\_{\\text{c}}\\approx7.8$ K, with $B\\_{\\text{c1}}\\approx 0.06$ T, $B\\_{\\text{c2}}\\approx 0.26 $ T, $\\kappa\\sim 2$ and weak flux pinning. The data are well described by the s-wave BCS model with weak electron-phonon coupling in the clean limit.
