Abstract

We fabricated a mini-superconducting bulk magnet of 200 mm × 100 mm, consisting of 18 square bulks, 33 mm on a side and 10 mm in thickness, and magnetized the mini-magnet by field cooling. The mini-magnet showed the trapped magnetic field of larger than 0.1 T on the surface of the outer vessel of the magnet. The present preliminary study discusses the possibility of superconducting bulk magnets for the Maglev system, and trapped magnetic field properties of the mini-bulkmagnet using YBaCuO superconductors at 77K.
