Significant interest has been shown on the encapsulating of carbon nanotubes(CNTs) with various metals. Especially, encapsulation ferromagnetic metal nanowire into CNTs would be very important due to their magnetic properties and the interesting structural phases that may exist in the nanoscale regime. Here, we report the synthesis of FeCo magnetic nanowires inside CNTs by a DC plasma chemical deposition(CVD). The detailed characterization of FeCo metal nanowires inside CNTs is transmission electron microscopy(TEM) and off-axis electron holography. The magnetic properties such as coercivity, saturation magnetization and magnetic anisotropy have been measured. FeCo nanowires inside CNTs has attracted much interest because of their strong perpendicular anisotropy at the surface or interface and technologically useful applications to information storage.
