The Research Group led by Professor Shindo (Institute of Multidisciplinary Research for Advanced Materials, Tohoku University)successfully demonstrated observations of a magnetic microstructure in a Co-CoO obliquely evaporated tape using electron holography. The reconstructured phase image demonstrated a periodic pattern of magnetic flux loops that were inclined to the film normal due to a well-developed columnar structure. The observations were supported by a computer simulation in which the effect of the stray magnetic field was considered. It is expected that this technique can be applied to magnetic imaging for other magnetic devices as well. This research achievement was accepted and published in Journal of Electron Microscopy in January, 2009.
