The author has been emphasizing the importance of adopting refrigerators to keep the superconductivity instead of using cryogen such as liquid nitrogen, since the handling of cryogen requires complicated skills and does not fit to the widespread industries. An intense field of 5.2 T has been obtained through the studies on the pulsed field magnetization process operated at 28 K. Several kinds of practical applications, for instance, the magnetron sputtering cathodes, the nuclear magnetic resonance NMR equipments, and magnetic separation systems, and so on are under way with use of the melt-processed large grain bulk magnets and cryo-coolers.
