REBCO melt-growth bulks, capable of trapping high magnetic fields, are expected to be used as powerful superconducting magnets. We have developed Single-Direction Melt Growth method, which enables reproducible, short-time growth of bulks, and direct growth of ring bulks especially for applications like desktop NMR. This presentation mainly discusses magnetization results of four stacked YBCO bulks, grown from a ring pellet with a 50 mm outer and 25 mm inner diameter.
