| Research Abstract |
We have developed a scanning SQUID probe microscope, which can image the local magnetic field by using a superconducting quantum interference device with a high spatial resolution. Toward the local nuclear magnetic resonance (NMR) measurements, we combined the scanning SQUID probe microscope with a low magnetic field NMR technique. We built a basic instrumental setup, which kept the probe-sample distance constant by atomic force microscopy under low magnetic fields. However, the magnetic coupling between the probe and the SQUID was too bad to get the enough sensitivity as the needed microscope performance. We newly fabricated the rf-SQUID which could be operated without a substrate resonator as the one solution.
