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.

The apparatus comprises a memory substrate having a stripe-shaped magnetic domain, a way to write Bloch lines in the magnetic wall of the stripe-shaped magnetic domain according to input information, a way to read the Bloch lines so stored to reproduce the information in the form of electric signals and a way to apply a rotating magnetic field parallel to the plane of the memory substrate, to the stripe-shaped magnetic domain, to move the Bloch lines along the magnetic wall. As a result, the Bloch lines so written are transferred in succession to another location in the domain or to a read-out area.
