We developed a simple single-direction melt growth for the fabrication of high-performance REBa 2 Cu 3 O y (RE: rare earth element) melt-textured bulks with selective grain growth. In this method, bulks were epitaxially melt-grown from a large plate cut from commercial melt-textured bulks by utilizing the different peritectic temperatures of REBa 2 Cu 3 O y . Ag-added YBa 2 Cu 3 O y bulks with three crystallographic orientations ([100], [110], and [001]) were successfully prepared. The whole c -grown bulk showed a higher trapped field (∼0.39 T) with more circular distributions than the conventional top-seeded bulk. The proposed method is promising for the fabrication of high-performance melt-textured bulks with high scalability and flexibility.
