Abstract

Wires of Pb0.6Sn0.4Mo6S8 with a protective sheet of Niobium have been carefully drawn and the critical current density Jc has been measured on small coils in magnetic fields up to 24 tesla. At 1.9K, the overall JCO, exceeds 100 A/mm2 at 20 tesla and 60 A/mm2 at 24 tesla. These large values highlight the good sintering between all the grains. However, the field dependence of JC still indicates that the effective upper critical field Bc2 is too low especially at 4.2K (31.5 tesla instead of 50 tesla).
