| Research Abstract |
In this study, significant improvement of the measurement sensitivity of high-frequency electron spin resonance (ESR) using a cantilever in the terahertz region is achieved. In particular, in order to detect small cantilever deflection due to ESR absorption, Fabry-Perot interferometer technique using a fiber-optic system is developed. We succeeded in ESR detection of magnetically isotropic radicals in the high-frequency region for the first time. A spin sensitivity of 108spins/G is achieved.
