Résumé

Light rare earth (neodymium, samarium, europium, gadolinium)-BCO bulk superconductors melt-processed in a reduced oxygen atmosphere are very promising for high field application as a superconducting permanent magnet with the liquid nitrogen refrigeration. Compared to a good quality melt-grown YBCO bulk, these bulks exhibit larger critical current density in high magnetic field and much improved irreversibility field at 77 K, implying that more effective flux pinning can be realized in a commercially feasible way. The authors report melt processing for these bulk superconductors and their characteristic superconducting properties.
