摘要: In this work we report the study of chemical solution deposited (CSD) YBa2Cu3O7-δ (YBCO) nanocomposite thin films, with diluted Ba2YTaO6 (BYTO) nanoparticles. We studied influence thermal treatment on properties nanocomposites, different content secondary phases (6%, 10% and 20%). measured film microstructure, nanostrain superconducting properties: critical temperature (Tc) current density (Jc). The films were characterized using X-rays diffraction SQUID inductive measurements. use two steps in allowed to increase up 0.30% for high nanoparticle loads (20%BYTO), decrease size down 15 nm lead a smoother Jc(H) dependence, compared standard (single-step) process pristine YBCO films.
