Abstract
A rapid and low-temperature process to obtain YBa2Cu3O y superconducting thin film was studied using a laser annealing technique. As-deposited thin film prepared by ion beam sputtering was converted into the superconductive film using argon laser beam processing, where melting, quenching to 400°C and annealing at 400°C in air were carried out. The onset critical temperature was 80 K and the end-point critical temperature was 60 K. Structure, composition and surface morphology were studied by X-ray diffraction, electron probe micro-analysis and scanning electron microscope.Keywords
