Research Abstract |
For the development of national strategy materials including permanent magnet and for that of thin magnetic ribbons to reduce environment load, a photographic imaging equipment for mm-order magnetic domain observation was successfully realized based on longitudinal Kerr effect. This system has an effective aperture dia. of 15 mm by using large relay lens with focal length of 125 mm (FL), objective lens with effective dia. of 50 mm and FL of 75 mm, and galvano-scanner with deflection angle of 8 deg. This system has enabled the time-resolved domain observation with magnetic moment direction for a power transformer with tape-wound core.
