Abstract

MoSi2-doped MgB2 tapes with different doping levels were prepared through the in situ powder-in-tube method using Fe as the sheath material. The effect of MoSi2 doping on the MgB2/Fe tapes was investigated. It was found that the highest JC value was achieved in the 2.5 at.%-doped samples, more than a factor of 4 higher than the undoped tapes at 4.2 K, 10 T, then further increasing the doping ratio caused a reduction of JC. Moreover, all doped tapes exhibited improved magnetic field dependence of JC. The mechanism of JC enhancement by MoSi2 doping is also discussed.
