MAGNETISM NANOWIRE INCLUDING A MAGNETIC DOMAIN WALL AND A METHOD FOR CONTROLLING THE MAGNETIC DOMAIN WALL IN THE MAGNETISM NANOWIRE, CAPABLE OF EASILY FIXING AND RELEASING THE MAGNETIC DOMAIN WALL

摘要

PURPOSE: A magnetism nanowire including a magnetic domain wall and a method for controlling the magnetic domain wall in the magnetism nanowire are provided to simply control the structure of the magnetic domain wall by adjusting the direction of currents injected in the magnetism nanowire.;CONSTITUTION: Magnetism nanowire includes a body part(10), a magnetic domain wall generating part(50), a magnetic domain wall generation controlling part(60), and a mark(30). The body part includes a first fixed magnetic layer(22), a non-magnetic layer(24), and a second free magnetic layer(26). The magnetic domain wall generating part is arranged on one side of the body part. The magnetic domain wall generation controlling part is arranged on another side of the body part. The mark is formed on one lateral side of the body part.;COPYRIGHT KIPO 2011
