Emergence of Giant Magnetic Chirality during Dimensionality Crossover of Magnetic Materials
Dae-Yun Kim, Yun-Seok Nam, Younghak Kim +12
Chirality, an intrinsic preference for a specific handedness, is a fundamental characteristic observed in nature. In magnetism, magnetic chirality arises from the anti-symmetric Dz…
Orbital Dynamics in Centrosymmetric Systems
Seungyun Han, Hyun-Woo Lee, Kyoung-Whan Kim
Orbital dynamics in time-reversal-symmetric centrosymmetric systems is examined theoretically. Contrary to common belief, we demonstrate that many aspects of orbital dynamics are q…
Theory of Kondo suppression of spin polarization in nonlocal spin valves
Kyoung-Whan Kim, Liam O'Brien, Paul A. Crowell +2
We theoretically analyze contributions from the Kondo effect to the spin polarization and spin diffusion length in all-metal nonlocal spin valves. Interdiffusion of ferromagnetic a…
Perpendicular magnetic anisotropy of two-dimensional Rashba ferromagnets
Kyoung-Whan Kim, Kyung-Jin Lee, Hyun-Woo Lee +1
We compute the magnetocrystalline anisotropy energy within two-dimensional Rashba models. For a ferromagnetic free-electron Rashba model, the magnetic anisotropy is exactly zero re…
Current-induced motion of a transverse magnetic domain wall in the presence of spin Hall effect
Soo-Man Seo, Kyoung-Whan Kim, Jisu Ryu +2
We theoretically study the current-induced dynamics of a transverse magnetic domain wall in bi-layer nanowires consisting of a ferromagnet on top of a nonmagnet having strong spin-…
