Outline of Final Research Achievements |
We have succeeded in preparing superconducting fullerene nanowhiskers by alkali metal doping for the first time. The whisker-like fullerenes have produced using liquid-liquid interfacial preparation method developed by Dr. Kun’ichi Miyazawa. The alkali metal doping reaction rate was done in a much shorter time than the previously reported doping to fullerenes. In addition, the critical current density was evaluated using the Bean model and it showed lager than 100000 A/cm2. These superior properties were considered to be because nanopores in whiskers play a major role. This research has just begun. Although there are still many challenges in making them wire, we would like to continue developing them as a very light and flexible superconducting fibrous material.
