  • Abstract
    Stainless steel sheathed MgB2 tapes with Cu addition were fabricated by PIT method. The influence of Cu content on microstructure and the critical-current density (Jc) of the tapes has been studied. The Jc value of MgB2 tapes was increased from 1500 A/cm2 to 4500 A/cm2 at 4.2 K and 5 T due to Cu addition. Jc-B curves show enhancement in Jc(B), which suggests that the microstructure and transport properties of MgB2 have been improved with Cu addition.
