Abstract

In this letter we demonstrate a synthetic route to thick (5-20 μm) highly c-axis textured, nearly phase-pure superconducting (Tl,Pb)(Ba,Sr) ₂Ca₂Cu₃O₉/Ag_0.37 tapes. First, a Tl-free ink consisting of Pb_0.5Ba_0.4Sr _1.6Ca_2.0Cu_3.0O₉/Ag_0.37 precursor powder in an ethanolic ethyl cellulose binder is sprayed onto a heated LaAlO₃ substrate. After an intermediate oxygen anneal to remove the carbonaceous binder, a static 2-zone thallination anneal is performed to promote superconducting phase formation. Films exhibit excellent c-axis texturing as evidenced by x-ray diffraction θ/2θ and rocking curve characterization with morphological evidence for partial melting by scanning electron microscopy. Electrical characterization of these films give T _c onset values of 106-115 K with T_c zero reached by 99-101 K and transport J_c(77 K) up to 2.9×10⁴ A/cm ². A mixed strong/weak-linked magnetic field dependence is observed for these films at 77 K and 0.4 T.
