Experimental Verification of Comparability between Spin-Orbit and Spin-Diffusion Lengths
Yasuhiro Niimi, Dahai Wei, Hiroshi Idzuchi +3
We experimentally confirmed that the spin-orbit lengths of noble metals obtained from weak anti-localization measurements are comparable to the spin diffusion lengths determined fr…
Towards coherent spin precession in pure-spin current
Hiroshi Idzuchi, Yasuhiro Fukuma, YoshiChika Otani
Non-local spin injection in lateral spin valves generates a pure spin current which is a diffusive flow of spins (i.e. spin angular momentums) with no net charge flow. The diffusiv…
Current-induced vortex-vortex switching in a nanopillar comprising two Co nano-rings
T. Yang, A. Hirohata, M. Hara +2
We fabricated a current-perpendicular-to-plane pseudo-spin-valve nanopillar comprising a thick and a thin Co rings with deep submicron lateral sizes. The dc current can effectively…
Current-induced vortex displacement and annihilation in a single Permalloy disk
T. Ishida, T. Kimura, Y. Otani
The induced motion of a magnetic vortex in a micron-sized ferromagnetic disk due to the DC current injection is studied by measuring planar Hall effect. The DC current injection is…
Current-induced Vortex Motion by Spin-Transfer Torque
Junya Shibata, Yoshinobu Nakatani, Gen Tatara +2
We investigate the dynamics of a magnetic vortex driven by spin-transfer torque due to spin current in the adiabatic case. The vortex core represented by collective coordinate expe…
