Abstract
We present a study of superconducting and microstructural properties of [00 1] tilt YBa2Cu3O7-delta (YBCO) thick film grain boundaries (GB) on SrTiO3 b icrystal substrates prepared using BaF2 er-situ post deposition reaction pr ocess. For a 15 degrees tilt boundary, multiple micro-bridges were patterne d across the grain boundary at various locations, A large variation of loca l critical current density J(c) was observed. Through local microstructural characterization of these GB bridges using transmission electron microscop e (TEM), a direct correlation of local GB J(c) with structure is identified .
