Method of operating information storage device using magnetic domain wall movement |
摘要 |
A method of operating an information storage device using a magnetic domain wall movement in a magnetic nanowire is provided. The magnetic nanowire includes a plurality of magnetic domains and pinning sites formed in regions between the magnetic domains. The method includes depinning the magnetic domain wall from a first pinning site by applying a first pulse current having a first pulse current density to the magnetic nanowire and moving the magnetic domain wall to a second pinning site by applying a second pulse current having a second pulse current density to the magnetic nanowire. The first pulse current density is greater than the second pulse current density. |
