| Research Abstract |
A high-speed and high-sensitive laser scanning magneto-optical microscope has been developed as a diagnostic apparatus and an optical output interface for magnetic devices. Using this system we have succeeded in the fast and quantitative imaging of a magnetic field distribution in superconductor devices with a sensitivity of ～100μT, and also succeeded in the detection of a single flux quantum generated in a superconducting loop. Furthermore, we succeeded in the imaging of weak magnetic field distribution around superconducting strip-line applied with a current as small as ～1mA by means of ac-modulation technique.
