Role of Bound Magnon in Magnetic Domain Wall Motion
Tae-Suk Kim, J. Ieda, S. Maekawa
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 dynamic…
Enhanced Domain Wall Motion in the Spin Valve Nanowires
Tae-Suk Kim
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 va…
Nonlocal Spin Transport in Lateral Spin Valves with Multiple Ferromagnetic Electrodes
Tae-Suk Kim, Hyun-Woo Lee, B. C. Lee
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 a…
Magnetoresistance in Spin-Polarized Transport through a Carbon Nanotube
Tae-Suk Kim, Choong-Ki Lee, Hyun-Woo Lee +2
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 s…
Effect of ferromagnetic contacts on spin accumulation in an all-metallic lateral spin-valve system: Semiclassical spin drift-diffusion equations
Tae-Suk Kim, B. C. Lee, Hyun-Woo Lee
We study the effect of the ferromagnetic (FM) contacts on the spin accumulation in the lateral spin valve system for the collinear magnetization configurations. When an additional…
Local Hall effect in hybrid ferromagnetic/semiconductor devices
Jinki Hong, Sungjung Joo, Tae-Suk Kim +5
We have investigated the magnetoresistance of ferromagnet-semiconductor devices in an InAs two-dimensional electron gas system in which the magnetic field has a sinusoidal profile.…
