Description
State-of-the-art deforming techniques allow the preparation of composite Bi-2223/Ag tapes with well controlled filament arrangement. This would allow tailoring of the tape's electromagnetic properties according to specific applications. We studied the possibility to reduce, through a suitable filament ordering, the hysteresis losses caused by an external magnetic field perpendicular to the tape's wide face. For this purpose, the distribution of shielding electrical currents in multifilamentary superconducting arrays, as a response to a perpendicular AC magnetic field, was investigated both theoretically and experimentally. We show that due to optimizing of filament arrangement, the hysteresis loss can be suppressed by one order of magnitude
