| Research Abstract |
The magnetic head for hard disk writing is attached to a probe of the probe-piezodriving specimen holder for transmission electron microscopy (TEM), in order to develop the dynamic magnetic field observation technique of TEM. In order to establish this technique, the magnetic field generated by a magnetic head was evaluated directly by electron holography technique. Moreover, in actual magnetic domain structure observation, since the systematic sample preparation for observation was difficult, the trial which analyzes the interaction of a magnetic domain wall and the material defect produced artificially was performed.
