Outline of Final Research Achievements |
We have improved the spin sensitivity of force-detected high-frequency electron spin resonance spectroscopy. First, we expanded the dynamic range of the cantilever-based system by introducing the optomechanical control of the cantilever dynamics. A more substantial improvement was made in the new system using a silicon itride nanomembrane. The new system can be stably operated even at high magnetic fields. By detecting the thermally modulated magnetization, it enables the robust measurement of the fast-relaxing spin systems such as magnetic materials. This technique can be used as a practical method in many research fields.
