Control of Domain Wall Position by Electrical Current in Structured Co/Ni Wire with Perpendicular Magnetic Anisotropy
Tomohiro Koyama, Gen Yamada, Hironobu Tanigawa +6
We report the direct observation of the current-driven domain wall (DW) motion by magnetic force microscopy in a structured Co/Ni wire with perpendicular magnetic anisotropy. The w…
Dynamical pinning of domain wall in magnetic nanowire induced by Walker breakdown
Hironobu Tanigawa, Tomohiro Koyama, Maciej Bartkowiak +4
Transmission probability of a domain wall through a magnetic nanowire is investigated as a function of the external magnetic field. Very intriguing phenomenon is found that the tra…
Reduction of threshold current density for current-driven domain wall motion by shape control
A. Yamaguchi, K. Yano, H. Tanigawa +2
We investigated the aspect ratio (thickness/width) dependence of the threshold current density required for the current-driven domain wall (DW) motion for the Ni81Fe19 nanowires. I…
Effect of Joule heating in current-driven domain wall motion
A. Yamaguchi, H. Tanigawa, T. Ono +4
It was found that high current density needed for the current-driven domain wall motion results in the Joule heating of the sample. The sample temperature, when the current-driven…
