Abstract

PURPOSE:To stabilize a stripe magnetic domain with low consumption energy by providing a different magnetic domain stabilization contributing characteristic different in place of a magnetic domain stabilization pattern. CONSTITUTION:The strip magnetic domain 6 is formed in a magnetic garnet thin film 4 on a non-magnetic garnet substrate 2. Around the domain 6, a magnetic wall 8 exists. The vertical magnetizing film of a stripe state 12 (for example, consisting of Co-Cr) is formed on the magnetic thin film 4, and the thickness of it's first part 12a is formed thicker than that of it's second part 12b. The direction of magnetization in the magnetic domain 6 is upward, the direction of the magnetization of the film 4 outside of the magnetic domain 6 is downward, the direction of the film 12 is upward and the direction of a bias magnetic field HB is downward. As the part 12a of the film 12 is thick, the magnetic domain 6 is stabilized at the lower part of the film 12. When the bias magnetic field HB' smaller than the HB is impressed downward, the magnetic domain 6 is stabilized at the lower parts of the both 12a and 12b. The tip part of the magnetic domain is taken out without high power consumption by properly selecting the HB'.
