| Abstract | The Bitter method is most commonly observing way of the magnetic domains situation even though it is possible to observe only the surface of specimen.To observe the magnetic domains by Bitter method, magnetic liquid is put on the target magnetic material after electrical field polishing process.Applying magnetic field to this magnetic material covered by magnetic fluid makes it possible to observe the magnetic domain dynamics by a microscope. We have previously reported that local magnetization characteristics could be obtained from the visualized magnetic domain dynamics. Final purpose of our research on visualized magnetic domain dynamics is to work out a fully automatic quality control system for the thin magnetic materials by visualizing the magnetic domain dynamics. In the present paper, we try to extract the magnetic domain locations exhibiting frequency fluctuation movement from the dynamic magnetic domains because it may be considered one of the causes of magnetic noise as well as chaotic behaviors. |
