Abstract
Wires of Pb0.6Sn0.4Mo6S8 with a protective sheet of Niobium have been carefully drawn and the critical current density J(c) has been measure d on small coils in magnetic fields up to 24 tesla. At 1.9K, the overa ll J(co), exceeds 100 A/mm(2) at 20 tesla and 60 A/mm(2) at 24 tesla. These large values highlight the good sintering between all the grains . However, the field dependence of J(c) still indicates that the effec tive upper critical field B-c2 is too low especially at 4.2K (31.5 tes la instead of 50 tesla).
