Outline of Final Research Achievements

Since there is little fluorescent dye that is effective for transition metals such as iron, copper, manganese and so on, it is impossible to enhance these species by optical microscope. In this study, we focused on electron spin in these compounds and we examined the optical detection of magnetic resonance. We successfully observed the ferromagnetic resonance of iron oxide nanoparticles via the change of the Faraday effect, an optical gyration phenomenon in magnetized materials. Therefore, we were able to demonstrate the principle of this technique. The exponential improvement of the spatial resolution in magnetic resonance techniques can be expected.
