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.

为了快速开发永磁体和减轻环境负荷的薄磁带等国家战略材料，研制了磁光探针功能分析系统。首先，我们成功建立了以下技术； (1) 通过成像板可视化磁性材料漏磁场的空间分布，以及 (2) 通过单次磁场扫描从局部区域对磁光效应谱（旋转角和椭圆率的波长依赖性）进行光谱检测。然后，将这些技术与磁性材料磁域中局部磁矩方向可视化技术相结合，完成了该评估系统。
