Abstract
The c-axis oriented single-domain Sm123 bulk superconductors have been synthesized in the melt-texturing process. The maximum trapped flux density has reached 1.7 T at 77 K and 9.0 T at 25 K at the center of sample surface. Detailed analysis on the flux motion through the pulsed field magnetization (PFM) process revealed that the iteratively magnetizing pulsed field operation with reducing amplitude (IMRA method) is very effective in magnetizing high Jc bulk superconductors at temperatures near 30K, attained by a cryocooler and vacuum pumps. A compact superconducting permanent magnet system driven by the PFM technique has been constructed, which is capable of generating magnetic fields up to 2 T in the open space outside the magnetic pole.
