| Outline of Final Research Achievements |
We have developed a scheme for nuclear magnetic resonance with both sensitivity and spatial selectivity by using hyperpolarization (highly polarized nuclear spin system) localized at the surface (interface) of a material (hyperpolarization labeling). Based on the optical pumping nuclear magnetic resonance system developed by ourselves, we have developed the following systems indispensable for the scheme: (1) a sample stage and its mounting system, (2) a light source system, (3) a light delivery system, and (4) a light control system. With the systems developed, we have demonstrated the selective detection of nuclear magnetic resonance signals from nuclei in the vicinity of the heterojunction in a gallium-arsenide-based heterostructure, by which the effectiveness of the scheme has been demonstrated.
