Cobalt‐filled carbon nanotube composites (see Figure) with a high metal‐filling ratio can be prepared by a simple and effective method. The length, diameter, and structure of the metal‐filled nanotubes and the wall thickness of the plain carbon nanotubes can be easily controlled by the template used and synthesis conditions. Magnetic measurements reveal that the array of cobalt‐filled carbon nanotubes exhibits enhanced coercivities in comparision to that of bulk Co.
