Abstract
- Abstract: Recent enlargement of the size and the performance enhancement of bulk superconductor lead to the difficulty of magnetic flux trapping by a pulsed-field magnetization. This paper proposes the bulk material with small holes which makes the role of an artificial magnetic flux path to supply the flux in the bulk. The fundamental experiment of applying a single pulsed-field with varying amplitudes was carried out using a ∅60mm × 20mm GdBa2Cu3O7− x bulk material with four ∅2mm holes filled up with solder. Compared with a usual hole-less bulk, the total magnetic flux and the maximum trapped flux density were greatly increased in a low applied field. Moreover, those large reduction caused by flux flow was suppressed in a high applied field. [Copyright &y& Elsevier]
