| Outline of Final Research Achievements |
We have succeeded in extending the frequency region of piezo-resistive micro-cantilever ESR up to 1.1 THz, which is the world record for such micro-cantilever ESR measurement. Moreover, we have developed a new micro-cantilever ESR system with much higher sensitivity by using the Fabry-Perot interferometer, which enables the detection of the displacement of micro-cantilever with high accuracy. Using this new micro-cantilever ESR system, we have succeeded in observing high frequency ESR of hemin (about 100 ng), which is the active center of hem protein, up to 0.5 THz. Multi-frequency ESR measurements of hemin have enabled us to obtain the zero-field splitting parameters in details.
