Magnesium‐diboride‐coated carbon nanotube arrays are synthesized by templating carbon‐nanotube aerogel sheets with boron and then converting the boron to MgB 2 . The resultant MgB 2 ‐CNT sheets are twisted into flexible, light‐weight yarns that have a superconducting transition around 37.8 K and critical current and critical field comparable with those of existing MgB 2 wires, but have about 20 times lower density than bulk MgB 2 .
