摘要：

The alternating-current (ac) losses in the Ag-sheathed (Bi,Pb)2Sr2Ca2Cu3Ox multifilamentary tapes with the filament number equal to 7, 19, 37, and 61 are investigated through an inductive method at 77 K under ac magnetic fields with the frequency 50 Hz≤f ≤700 Hz and the field amplitude 2 mT≤B0≤50 mT, and the results are compared with those for a monofilamentary tape. The subdivision of superconductor into multifilaments suppresses the hysteresis loss within the filaments, which is the main contribution to the ac losses in the monofilamentary tape. However, the enhancement of the eddy current loss in the multifilamentary tapes makes the ac losses comparable to those in the monofilamentary tapes.© 1995 American Institute of Physics.
