Abstract :
The authors synthesized a single crystal of the high-critical-field compound SnMo6S8 to serve as a model of the superconducting behavior of Pb1-xSnxMo6S8 in wires and bulk samples. Magnetization critical current densities were measured in fields up to 11 T at various temperatures from 3.1 to 7 K. The behavior of the single crystal was compared to that of bulk and wire samples as well as to oxide superconductors. Significant field-induced flux pinning is found to occur within a single crystal of SnMo6S8 . It is suggested that these pinning centers are atomic-scale defects
