✦ Synopsis

The deposition of nickel/amorphous carbon (Ni/a-C) films by a hybrid plasma process combining magnetron sputtering of a Ni target and plasma enhanced chemical vapor deposition using methane gas has been investigated. The formation of nickel nanowires encapsulated by a-C matrix has been demonstrated by transmission electron microscopy (TEM). The obtained nanowires array can be easily dispersed or can be simply converted to a Ni-filled CNT array by annealing at 350 °C as confirmed by TEM analysis. The developed fabrication method of Ni-filled CNT array is a low temperature technique compatible with substrates of low melting point.

## Abstract Ferromagnetic‐filled carbon nanotubes are new nanostructured materials with many possible applications. They can be synthesized using the thermal decomposition of metallocenes of the iron triad. Two different methods (solid and liquid source CVD) are suitable for producing, at very high
