Iron-filled carbon nanotubes (Fe@CNTs), in which iron (Fe) nanowires fill the cavities of carbon nanotubes (CNTs), are promising as hard ferromagnetic materials. In this study, palladium (Pd)/iron (Fe) multilayered thin films were used as catalyst thin films for the growth of Fe@CNTs. High coercivity was observed when the Pd layer thickness was approximately 0.5 nm or less, reaching a maximum of 1.95 kOe. These results suggest that the stacking of the Pd layer affects the crystal magnetic anisotropy of the nanowires in Fe@CNTs.
