| Outline of Final Research Achievements |
For development of high performance electric car motors consisting of permanent magnets and thin magnetic ribbons to reduce environment load, a spectroscopic imaging system with a magneto-optical probe for a magnetic domain structure and a spatial magnetic field distribution was successfully realized. Established and combined techniques were as follows; (1) visualization of the dynamics of magnetic domain structure for samples with scratches by real-time processing of differential-polarization images with two analogue cameras, (2) analysis of the three-dimensional local magnetization components due to imaging with the oblique incidence from the opposite directions, (3) high sensitivity imaging by a backside-illuminated CMOS camera, and (4) detection of magneto-optical spectra by using an imaging device.
