Research Abstract |
In order to rapidly develop the national strategic materials used for permanent magnet and thin magnetic ribbons which could reduce the environment load, a functional analysis system with magneto-optical probe was developed. First, we had successfully established the following techniques; (1) visualization of the spatial distribution of the leak magnetic field from a magnetic material by an imaging plate, and (2) spectroscopic detection of magneto-optical effect spectrum (wave length dependence of rotation angle and ellipticity) from local area with a single sweep of the magnetic field. Then, this evaluation system was completed with combining these techniques with a technique of visualization of local magnetic moment direction in magnetic domain of the magnetic material.
