抄録

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, lc of the tape was increased. To elucidate whether Li doping increases the lc 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 lc by 10%, which is consistent with the bulk data. As a result of lc-B measurement at a temperature of 4.2 K, it was found that lc/lc(O 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.
