| Outline of Final Research Achievements |
Iron-filled carbon nanotubes (Fe@CNTs) show excellent magnetic properties such as high coercivity. It is expected that formation of bulk comprising the Fe@CNTs enables creation of a flexible and lightweight permanent magnet, which realize enhancement of performance and low power consumption of various electrical equipments such as motors. This study focused on the following two points to realize the fabrication of the Fe@CNT bulk magnet: (i) to synthesize the Fe@CNTs with higher magnetic property, (ii) to develop the method for fabrication of Fe@CNT bulk material. We confirmed that the coercivity of Fe@CNTs can be enhanced by using oxidized nickel catalyst film. In addition, we developed the novel method for the efficient formation of filaments that comprise aligned Fe@CNTs using gas discharge breakdown. The results of this study indicate that the formation of the formation of bulk comprising Fe@CNT with high coercivity is possible.
