| Research Abstract |
In this study, a simultaneous measurement system for observation of domain wall movement and detection of induced voltage at pickup coil was developed. On the other hand, the relationships between magnetic domains and lattice defects were clarified experimentally when the micro lattice defects were introduced into the specimen. The defects pinned domain walls and affect the configurations of magnetic domains and behaviors of domain wall movements. The feasibility of controlling the local domain structures and local magnetic characteristics was indicated.
