We have assessed various superconducting materials for NMR application, and designed and fabricated a compact, lightweight, mobile permanent high-Tc superconducting magnet system using RE annular bulk. Using this bulk magnet system, we successfully magnetized several melt-processed bulk samples at 77 K. Additionally, we experimentally produced a compact NMR magnet system using RE annular bulks and tapes. Using simple superconducting magnets for magnetizing bulk materials can open new technological windows in various industrial areas.
