Abstract

PURPOSE:To surely execute the respective operation of writing/reading, replication and erasing by surely generating a vertical Bloch line-VBL at the end part of a desired magnetic domain after a chopping margin in a state obtaining the big chopping margin. CONSTITUTION:A minor loop ML consisting of the magnetic wall of the stripe magnetic domain formed on the vertical magnetizing film 11 of a Bloch line memory storing a signal is formed. Then, at the one end of the loop ML, a first gate part 21 for writing or reading is disposed and a second gate part 22 for erasing is disposed at the other end. A chopping conductor 4 consisting of a pair of parallel conductor 4a and 4b is formed at the respective gates 21 and 22 and the conductors 4a and 4b are inversely charged. Besides, the positional relation of the loop ML and the gates 1 and 22 is selected so as to orient the direction of an in-plane magnetic field along the film plane of the magnetizing film 11 made by the conductor 4a or 4b at the loop ML side toward the direction of magnetization in the magnetic wall of the chopping conductor 4.
