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…
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…
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…
Magnetic droplet nucleation with homochiral Neel domain wall
Sanghoon Kim, Peong-Hwa Jang, Duck-Ho Kim +5
We investigate the effect of the Dzyaloshinskii Moriya interaction (DMI) on magnetic domain nucleation in a ferromagnetic thin film with perpendicular magnetic anisotropy. We propo…
