Abstract:
A magneto-optical imaging technique has been employed to visualize magnetization processes of soft magnetic composite material. The profiles of reflected light intensity of magneto-optical images at the sample surface were plotted. The results demonstrate that magnetooptical imaging is a sensitive tool to visualize magnetization process. The flux profiles obtained under conditions of perpendicular and tangential magnetizations indicate that the sample behaves as a collection of individual magnetized particles rather than as a uniform and continuous magnetic substance.
