    摘要： A method of transferring Bloch lines present in a domain wall of a magnetic domain formed in a thin magnetic firm, includes cyclically forming asymmetrical potential wells along the domain wall in order to locate the Bloch lines at predetermined positions of the domain wall, and applying a pulsed magnetic film to shift the Bloch lines from a predetermined potential well to another potential well. In a magnetic memory for recording information using Bloch lines as an information carrier, a memory substrate has a stripe magnetic domain defined by a domain wall along which asymmetrical potential wells are cyclically formed to stabilize the Bloch lines along the domain wall. The Bloch lines are written in the domain wall in accordance with input information, the Bloch lines so formed are read out, and the read-out Bloch lines are converted into an electrical signal. A pulsed magnetic field is applied in a direction perpendicular to a surface of the memory substrate for shifting the Bloch lines between potential wells.

    摘要： 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.

    摘要： Method for transferring the Bloch line present in the magnetic wall of the magnetic domain formed in the magnetic thin film, along the magnetic wall is characterized by the steps of forming a predetermined stress distribution along the magnetic wall in the magnetic thin film, positioning the Bloch line to a predetermined position in the magnetic wall in accordance with the stress distribution, and applying a pulsive magnetic field normally to a film plane of the magnetic thin film in synchronism with the formation of the stress distribution. The Bloch line is transferred from the predetermined position to another position by the stress distribution formation step and the magnetic field application step.
