Abstract

A superconducting F-doped Hg_xBa₂Ca₂Cu₃Re_0.2O _y filament was produced by a two-step method. The precursor Ba₂Ca₂Cu₃Re_0.2O_x filament was fabricated using a solution spinning method and reacted in an evacuated fused quartz tube with a pellet of Hg₁Ba_1.8Ca₂Cu₃Re _0.2(BaF₂F₂)_0.2O_x. The influence of fluorine on the transport J_c of the F-doped Hg1223 filament at 77 K was examined in magnetic fields of up to 10 T. F-doping resulted in a formation of dense liquidus texture and marked improvement in the field dependence of J_c for the filament. A J_c of more than 10² A/cm² was maintained at 77 K in a field of 10 T.
