ABSTRACT:
A Bloch line transferring method or system comprises a step of transferring only a first Bloch line of the Bloch line pair in the magnetic wall in a predetermined direction, and a step of transferring a second Bloch line of the Bloch line pair in the predetermined direction to form the Bloch line pair. It typically comprises applying a magnetic field perpendicular to a film plane of a magnetic thin film having the magnetic wall, to the magnetic thin film, and applying a magnetic field parallel to the film plane of the magnetic film, to the magnetic thin film along the magnetic wall.
