Abstract

PURPOSE:To realize stable and certain Bloch line transfer by forming a potential for controlling the position of a Bloch line whose extremal value moves in one direction along a magnetic wall, and quasistatically transferring the Bloch line. CONSTITUTION:A Bloch line memory consists of a soft magnetic substance layer 12 formed on a non-magnetic garnet substrate 2, a magnetic garnet thin film 4, a strip state magnetic domain 6 and a film 4 in a pattern state through a spacer layer 14 and the magnetic wall 8. When a magnetic field rotating in the direction of a clock in the magnetic thin film 4 is impressed, the maximum or the minimum position of the (x) direction component Hx of the field generating in the L part of the magnetic wall 8 is moved to the left direction based on magnetization generated in the soft magnetic substance layer 12. As a set of Bloch line possess the magnetization of an (x) direction in the middle, it is stabilized at the maximum or the minimum position and successively moved to the left direction and the Bloch line is transferred. At the part L' of the magnetic wall 8, the movement of the extremal value position of the Hx directs the right, and finally the Bloch line is transferred to the opposite direction of a clock shown by an arrow T extending the whole magnetic wall 8.
