Actual critical current densities (Jc) obtained by most of the groups working on superconducting PbMo6S8 wires are about 2 × 108A/m2 at 4.2 K and 20 T. But Jc fluctuations along the wire length are still large. We present here a two-step heat treatm

Compensation of the paramagnetic effect on Hc2by magnetic moments: 700 kG superconductors
Autor: M. Sergent, Michel Decroux, S Roth, O Fischer, R Chevrel
Publikováno v: Journal of Physics C: Solid State Physics. 8:L474-L477
An increase of about 50-100 kG of the upper critical field is observed in Sn1.2(1-x)EuxMo6.35S8 and Pb1-xEux- Mo6.35S8 with respect to the compounds without Eu. This increase, due to the Jaccarino-Peter compensation effect, pushes Hc2 up into the vic

Measurements of critical fields up to 500 kG in the ternary molybdenum sulphides
Autor: G. Bongi, H. Jones, R Chevrel, M. Sergent, O Fischer
Publikováno v: Journal of Physics C: Solid State Physics. 7:L450-L453
Using slowly pulsed magnetic fields up to 510 kG it is shown that some lead-rich ternary molybdenum sulphides have critical fields above 500 kG, whereas the Sn-rich compounds have critical fields of the order of 300-400 kG.
