Enhanced perpendicular magnetocrystalline anisotropy energy in an artificial magnetic material with bulk spin-momentum coupling
Abdul-Muizz Pradipto, Kay Yakushiji, Woo Seung Ham +8
We systematically investigate the perpendicular magnetocrystalline anisotropy (MCA) in CoPt/Pd-based multilayers. Our magnetic measurement data shows that the asymmetric Co/Pd/P…
Enhanced spin-orbit torque via interface engineering in Pt/CoFeB/MgO heterostructures
Hae-Yeon Lee, Sanghoon Kim, June-Young Park +9
Spin-orbit torque facilitates efficient magnetization switching via an in-plane current in perpendicularly magnetized heavy metal/ferromagnet heterostructures. The efficiency of sp…
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…
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…
