Efficient conversion of orbital Hall current to spin current for spin-orbit torque switching

Soogil Lee, Min-Gu Kang, Dongwook Go +9

Spin Hall effect, an electric generation of spin current, allows for efficient control of magnetization. Recent theory revealed that orbital Hall effect creates orbital current, wh…

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…

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…
