Abstract
Superconducting permanent magnet systems generating magnetic fields of 2-5 T have been constructed for the first time in the world by c-axis oriented Sm-Ba-Cu-O bulk superconductors fabricated through the melt processing as trapped field magnets. The trapped magnetic fields of 3.8 and 6.7 T have been produced on the bulk surface at 30 K by the pulsed field magnetization (PFM) and field cooling (FC) methods, respectively. The magnetic field in the open space outside the vacuum vessel exceeds 2.0 and 3.2 T when magnetized by the PFM and FC modes, respectively. It was found that the iteratively magnetizing pulsed-field operation with reducing amplitudes (IMRA method) is very effective in magnetizing high Jc bulk superconductors. This implies the superconducting permanent magnets can be used as high magnetic field generators in various practical applications.
