Abstract

We present a study of superconducting and microstructural properties of [001] tilt YBa₂Cu₃O_7-δ (YBCO) thick film grain boundaries (GB) on SrTiO₃ bicrystal substrates prepared using BaF₂ ex-situ post deposition reaction process. For a 15° tilt boundary, multiple micro-bridges were patterned across the grain boundary at various locations. A large variation of local critical current density J_c was observed. Through local microstructural characterization of these GB bridges using transmission electron microscope (TEM), a direct correlation of local GB J_c with structure is identified.
