Effect of pulsed magnetic field on critical current in carbon-nanotube-doped MgB2 wires

This study is about carbon-nanotube (CNT)-doping of MgB2 superconductor processed under the magnetic field. The Jc(H) for CNT doped sample increased by a factor of 2—3 in low filed and more than an order of magnitude in high field after processing in magnetic field. The alignment of CNT along the processing field direction was observed by SEM.
