Role of orbital hybridization in anisotropic magnetoresistance
Hye-Won Ko, Hyeon-Jong Park, Gyungchoon Go +3
We theoretically and numerically show that longitudinal orbital currents in ferromagnets depend on the magnetization direction, which contribute to the anisotropic magnetoresistanc…
Numerical Computation of Spin-Transfer Torques for Antiferromagnetic Domain walls
Hyeon-Jong Park, Yunboo Jeong, Se-Hyeok Oh +5
We numerically compute current-induced spin-transfer torques for antiferromagnetic domain walls, based on a linear response theory in a tight-binding model. We find that, unlike fo…
Long spin coherence length and bulk-like spin-orbit torque in ferrimagnetic multilayers
Jiawei Yu, Do Bang, Rahul Mishra +14
Ferromagnetic spintronics has been a main focus as it offers non-volatile memory and logic applications through current-induced spin-transfer torques. Enabling wider applications o…
Dzyaloshinskii-Moriya interaction induced extrinsic linewidth broadening of ferromagnetic resonance
Jung Hyun Oh, Ik-Sun Hong, Kyung-Jin Lee
For a thin ferromagnetic film with the Dzyaloshinskii-Moriya interaction (DMI), we derive an expression of the extrinsic ferromagnetic resonance (FMR) linewidth in a quantum mechan…
Transport theory of coupled quantum dots based on auxiliary operator method
Jung Hyun Oh, D. Ahn, Vladimir Bubanja
We formulate the theory of electron transport through coupled-quantum dots by extending the auxiliary operator representation. By using the generating functional technique, we deri…
Klein tunneling through an oblique barrier in graphene ribbons
J. H. Oh, D. Ahn
We study a transmission coefficient of graphene nanoribbons with a top gate which acts as an oblique barrier. Using a Green function method based on the Dirac-like equation, scatte…
