Abstract
A Bloch line magnetic memory has a magnetic film of thickness h located on a substrate and includes Bloch lines of width .LAMBDA.o. The magnetic film satisfies the condition (1) h/.LAMBDA.o<14 with .LAMBDA.o=.sqroot.A/2.pi.Ms.sup.2, in which A represents the magnetic exchange constant and 4.pi.Ms represents the saturation magnetization of the film.
