| Outline of Final Research Achievements |
Graphite has been known as a typical diamagnetic material and can be levitated in the strong magnetic field. We found that the magnetically levitating pyrolytic graphite can be moved in the arbitrary place by simple photoirradiation. It is notable that the optical motion control system requires only NdFeB permanent magnets and light source. The optical movement is driven by photothermally induced changes in the magnetic susceptibility of the graphite. We found that light energy can be converted into rotational kinetic energy by means of the photothermal property. We analyzed the energy conversion efficiency and optimized the condition for increasing the rotational speed.
