| Outline of Final Research Achievements |
We produced nanocarbon (i.e. carbon nanotube and activated carbon fibers) composites with magnetic ionic liquid of 1-ethyl-3-methylimidazolium tetrachloroferrate. The composites show magnetic response even for magnetic fields of a neodymium magnet. The temperature dependence of magnetic susceptibility of the composites are different from that of the bulk ionic liquid: magnetic phase transition from paramagnetism to antiferromagnetism does not observed at 3.8 K. We applied hybrid reverse Monte Carlo (HRMC) simulation to confined magnetic ionic liquid system for the detailed structural analysis. Anomalous accumulation of tetrachloroferrate anion into the nearest coordination shell surrounding anion in carbon nanopore was observed, implying the unique magnetic behaviors.
