摘要：
A method for aligning carbon nanotubes (CNTs) in CNT-MgB2 superconductor composite wires through a readily scalable drawing technique is described. The aligned CNT-doped MgB2 wires show an enhancement in magnetic critical current density by more than an order of magnitude in high magnetic fields compared to undoped wires. The arrows in the figure indicate CNTs in the composite.
