| Popis: | The effect of preparation technique and pressure on the critical current densityj c for PbMo 6 S 8 and SnMo 6 S 8 is investigated. It is shown thatj c is significantly influenced by preparation technique. The lower limit forj c at 4.2 K is 2 · 10 4 A/cm 2 in a field of 80 kOe. Measurements of the pressure dependence of the critical currents are carried out in the 0–4 kbar pressure range at 4.2 K in magnetic fields up to 90 kOe. A strong decrease ofj c with pressure is observed. |
