摘要：
We report the successful fabrication of single-filament composite MgB2/stainless-steel ribbons, as an ultrarobust conductor type. The transport critical current of the non-sintered MgB2/stainless-steel ribbons is remarkably high, as an unexpected result. Transport critical currents I-c similar to 316 A at T = 4.2 K and I-c similar to 82 A at T = 20 K were observed at self-field for the non-sintered composite MgB2/stainless-steel ribbons. The I-c value of 316 A is the higher than any other value reported so far. In addition, the persistent current density, that was estimated by Bean formula, of the sintered composite MgB2/stainless-steel ribbons was more than J(p) similar to 6 x 10(5) A/cm(2) at T = 5 K with H = 0 G, and J(p) similar to 1.1 x 10(5) A/cm(2) at T = 30 K with H = 0 G.
