Description

For Bi-2223 Ag-sheathed tapes, pressing conditions between sintering were optimized. It was found that with an increase in the pressure from 1 t cm-2 to 10 t cm-2, Ic of the tape was increased. To elucidate whether Li doping increases the Ic of the tape as reported in the bulk sample, Li doping was carried out. It was found that doping of 0.1-0.3 at.% Li increased Ic by 10%, which is consistent with the bulk data. As a result of Ic-B measurement at a temperature of 4.2 K, it was found that Ic/Ic(0 T) of the 0.3 at.% Li-doped tape under a magnetic flux density of 10 T was 20% higher than that of the non-doped tapes.
