We report on a quantum description of the domain wall (DW) motion under a spin current. A bound magnon, which is the zero mode of DW, is found to play a dominant role in DW dynamics. The bound magnon acquires its inertia by the hard axis anisotropy a

Enhanced Domain Wall Motion in the Spin Valve Nanowires

Autor: Kim, Tae-Suk

According to the recent experiment by the Fert group, the velocity of domain wall motion in the spin valve ferromagnetic nanowires was almost doubly enhanced compared to the old value. In this work, we propose an additional torque model, arising from

Nonlocal Spin Transport in Lateral Spin Valves with Multiple Ferromagnetic Electrodes

Autor: Kim, Tae-Suk, Lee, Hyun-Woo, Lee, B. C.

Publikováno v: J. Kor. Phys. Soc. 53, 973 (2008)

We study the nonlocal spin transport in a lateral spin valve with multiple ferromagnetic (FM) electrodes. When two current-injecting and two spin current-detecting electrodes are all ferromagnetic, the number of possible nonlocal spin signal states i

Magnetoresistance in Spin-Polarized Transport through a Carbon Nanotube

Autor: Kim, Tae-Suk, Lee, Choong-Ki, Lee, Hyun-Woo, Lee, B. C., Rhie, K.

We report on our theoretical study of the magnetoresistance in spin polarized transport through a finite carbon nanotube (CNT). Varying the Fermi energy of a CNT and the relative strength of couplings to two ferromagnetic (FM) electrodes, we studied
