Abstract

Fast Temperature Ramping Annealing (FTRA) combined with a cation-exchange process is applied in the fabrication of HgBa₂Ca₁Cu₂O_x (Hg-1212) superconducting tapes on Rolling Assisted Biaxially Textured Substrates (RABiTSs). Tl₂Ba₂CaCu₂O_x (Tl-2212) precursor films were synthesized on RABiTSs and then converted into Hg-1212 films. By employing the FTRA process in the synthesis of Tl-2212 films, significant improvement was achieved in terms of surface morphology as well as in-plane alignment. These features were retained in the Hg-1212 films during Tl-Hg cation-exchange. T_c of Hg-1212 films is up to 124K and J_c is up to 10⁵A/cm² (0T) at 115K. Further improvements in J_c are expected for optimized synthesis conditions.
