ABSTRACT:
A Bloch line memory device comprises stripe magnetic domains in a magnetic film for holding magnetic bubble domains. A pair of Bloch lines is stored as an information carrier in a magnetic wall constructing the stripe magnetic domain. A longitudinal direction of the stripe magnetic domain is made parallel to either the crystalographic directions [112] and [112], [121] and [121], or [211] and [211] of the magnetic film so that the pair of Bloch lines can be smoothly moved in the magnetic wall of the stripe magnetic domain.
