Abstract
Increased critical current densities J c up to 2×104 A/cm2 at 4.2 K and 20 T were found for quaternary Chevrel-phase Pb1.2-xSnxMo6S 8 wires. Compared to the ternary compounds, the composition was varied over the whole mixing range, and the change of the crystal structure parameters Tc and J c was analyzed and discussed with respect to the observed J c enhancement. These results were obtained for different wire preparation techniques using unreacted or HIP (hot isostatically pressed) prereacted starting materials, but always the same current-stabilized (Cu) and steel-reinforced wire configuration. A very good reproducibility of the J c values indicates homogeneous material properties of the filaments and a uniform wire cross section
