11-6 垂直磁化磁性細線における複数磁区の一斉電流駆動(第11部門コンシューマエレクトロニクスおよびマルチメディアストレージ)

抄録

We have focused on new magnetic memories without mechanical moving parts, utilizing the current-driven magnetic domain wall motions, in order to achieve ultra high data transfer rate. We fabricated [Co/Pd] magnetic nanowire with perpendicular anisotropy, and succeeded to drive multiple magnetic domains along the nanowire by the applied current.
