Abstract
REBa 2 Cu 3 O 7-δ bulk superconductors are able to trap large magnetic fields and as a result they have potential to work as strong magnets. In this study, highly textured yttrium, gadolinium, and samarium based cuprate bulk superconductors were prepared using conventional top-seeded melt-textured growth, and magnetized by employing both field-cooling magnetization (FCM) and pulsed-field magnetization (PFM) techniques at 77 K. The same peak value of a trapped field was achieved using FCM and PFM, which means all the bulk samples were fully magnetized by using the PFM method. In addition, the magnitude of the pulsed field required to fully magnetize the bulk samples varied with rare-earth element in the (RE)BCO formulation.
