Abstract

Ba₂YCu₃O_7-x-BaZrO₃ superconductive composite was prepared by spray drying method. The composite sintered body had nano-composite structure consisting of Ba₂YCu₃O_7-x and intragrain BaZrO₃ particles with a less than 100nm size. The contribution of BaZrO₃ particles to flux pinning was discussed by microstructure observation and pinning property measurement of the sintered body.
