Coherent Terahertz Spin-Wave Emission Associated with Ferrimagnetic Domain Wall Dynamics
Se-Hyeok Oh, Se Kwon Kim, Dong-Kyu Lee +5
We theoretically study the dynamics of ferrimagnetic domain walls in the presence of Dzyaloshinskii-Moriya interaction. We find that an application of a DC magnetic field can induc…
Contributions of Co and Fe orbitals to Perpendicular Magnetic Anisotropy of MgO/CoFeB Bilayers with Spin-Orbit-Torque-Related (Ta, W, IrMn, and Ti) Underlayers
Sanghoon Kim, Seung-heon Chris Baek, Mio Ishibashi +9
We study the perpendicular magnetic anisotropy (PMA) of the CoFeB/MgO bilayers in contact with W, Ta, IrMn and Ti which has been suggested as the spin-orbit-torque-related underlay…
Distinct domain-wall motion between creep and flow regimes near the angular momentum compensation temperature of ferrimagnet
Yuushou Hirata, Duck-Ho Kim, Takaya Okuno +6
We investigate a magnetic domain-wall (DW) motion in two dynamic regimes, creep and flow regimes, near the angular momentum compensation temperature (T_A) of ferrimagnet. In the fl…
Origin of threshold current density for asymmetric magnetoresistance in Pt/Py bilayers
Tian Li, Sanghoon Kim, Seung-Jae Lee +7
An asymmetric magnetoresistance (MR) is investigated in Py/Pt bilayers. The asymmetric MR linearly increases with current density up to a threshold, and increases more rapidly abov…
Spin-orbit effective fields in Pt/GdFeCo bilayers
Woo Seung Ham, Sanghoon Kim, Duck-Ho Kim +6
In the increasing interests on spin-orbit torque (SOT) with various magnetic materials, we investigated SOT in rare earth-transition metal ferrimagnetic alloys. The harmonic Hall m…
Switching local magnetization by electric-field-induced domain wall motion
H. Kakizakai, F. Ando, T. Koyama +7
Electric field effect on magnetism is an appealing technique for manipulating the magnetization at a low cost of energy. Here, we show that the local magnetization of the ultra-thi…
