摘要：

A full account of positive-muon spin-rotation (mu+SR) studies on the systematics of the magnetic penetration depth lambda in the isotropic Chevrel-phase superconductors SnMo6S8-xSex (x=0,1,4,7) and PbMo6S8-xSex (x=0,4) is presented. The absolute determination of lambda from the muSR data necessitates a careful analysis of the muSR line shape and a comparison with simulated data, taking into account distortions of the flux-line lattice and a distribution of demagnetization factors in the sintered granular polycrystalline probes investigated. A correlation between T(c) and 1/lambda2 iS found which supports a recently developed quantum percolation model.
