| Outline of Final Research Achievements |
We developed ultrasensitive high-frequency electron spin resonance technique and terahertz magnetic resonance force microscopy. With use of fiber-optic Fabry-Perot interferometry, a tiny sample on the order of 100 ng could become possible. Our technique was applied to hemin, a model substance of hemoproteins in frequencies up to 0.5 THz, and precise determination of zero-field splliting parameters was made.
In addition, three-axis piezoelectric translational stage for low-temperature and high-field eperiments were developed. By sweeping a magnetic-tip holding cantilever over the sample surface, we succeeded in spatially resolved ESR measurements at liquid helium temperature.
