| Outline of Final Research Achievements |
Field-stepwise-swept solid-state nuclear magnetic resonance (NMR) method combined with high-temperature superconducting (HTS) coil, which is expected to be a powerful tool for increasing the S/N ratio in an NMR measurement, is developed. In a conventional NMR method, there is limitation of measurable NMR nuclei, such as 1H, 13C, 15N, and so on, because of the two problems: one is horizontal problem, which mainly arises from quadrupolar interactions, in some cases, making the spectral width of NMR spectra more than several megahertz. The other problem is vertical problem, which comes from the fact that lower Lamour frequency and/or a small spin density in samples make signal intensity lower. The present method can potentially resolve the above two problems simultaneously, indicating that all nuclei in the periodic table become NMR accessible nuclei.
