Correlation between Compensation Temperatures of Magnetization and Angular Momentum in GdFeCo Ferrimagnets
Yuushou Hirata, Duck-Ho Kim, Takaya Okuno +8
Determining the angular momentum compensation temperature of ferrimagnets is an important step towards ferrimagnetic spintronics, but is not generally easy to achieve it experiment…
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…
Microscopic Origin of Interfacial Dzyaloshinskii-Moriya Interaction
Sanghoon Kim, Kohei Ueda, Gyungchoon Go +15
Chiral spin textures at the interface between ferromagnetic and heavy nonmagnetic metals, such as Neel-type domain walls and skyrmions, have been studied intensively because of the…
