Quantum Spin Transfer of Spin-Correlated Electron Pairs
Seongmun Hwang, Jung Hyun Oh, Paul M. Haney +2
We theoretically investigate quantum spin transfer from spin-correlated conduction-electron pairs to localized spins in a ferromagnet, given that electrons are correlated intrinsic…
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 Pumping Incorporating Both Orbital Angular Momentum and Position
Seungyun Han, Hye-Won Ko, Jung Hyun Oh +3
We develop a theory of adiabatic orbital pumping, highlighting qualitative differences from spin pumping. An oscillating magnetic field pumps not only orbital angular momentum curr…
Orbital diffusion, polarization and swapping in centrosymmetric metals
Xiaobai Ning, A. Pezo, Kyoung-Whan Kim +3
We propose a general theory of charge, spin, and orbital diffusion based on Keldysh formalism. Our findings indicate that the diffusivity of orbital angular momentum in metals is m…
Chirality from interfacial spin-orbit coupling effects in magnetic bilayers
Kyoung-Whan Kim, Hyun-Woo Lee, Kyung-Jin Lee +1
As nanomagnetic devices scale to smaller sizes, spin-orbit coupling due to the broken structural inversion symmetry at interfaces becomes increasingly important. Here we study inte…
Spin torque and force due to current for general spin textures
Gen Tatara, Hiroshi Kohno, Junya Shibata +2
Non-adiabatic correction to spin transfer torque arising from fast-varying spin texture is calculated treating conduction electron fully quantum mechanically. The torque is non-loc…
