摘要

We prepared Ag-sheathed Bi2223 multifilamentary tapes having 19 filaments with three different barrier configurations by using the powder-in-tube method. The layers of Sr-V-O (SVO) barrier are arranged inside and/or outside of each filament. For the tapes with barriers the transport critical current I/sub c/ and its density J/sub c/ at 77 K are higher than those of the nonbarrier tapes for all the...
