Outline of Final Research Achievements

We develop optically detected magnetic resonance technique that overcomes conventional solid-state NMR methods and realize the unprecedented high sensitivity measurements for tiny samples. We have succeeded to measure zero-field and ultra-low-field (ZULF) NMR and established fundamental technique for highly sensitive magnetic probes. Utilizing alkali vapor cell magnetometers, we extend the capability of ZULF-NMR from low-viscosity liquids to high-viscosity liquids and polymer gels. We also demonstrate that ZULF-NMR is useful for microscopic observations of relaxation rates and intermolecular interactions.
