| Outline of Final Research Achievements |
We established a scanning nuclear-spin resonance method suitable for semiconductor quantum systems. To achieve this goal, we combined electrical-resistive detection and local nuclear resonance utilizing scanning probe. This technique allows us local detection of both nuclear resonance intensity and Knight shift proportional to the electron spin polarization in the quantum channel of the semiconductor system. To show powerful feature of our new technique, we use quantum Hall breakdown as a model system. We have succeeded to observe local nuclear polarization and electron spin polarization. Our technique open up new avenues for nano magnetic resonance imaging of various quantum devices.
