Negligible current-induced torque from the bulk and interface of Al
Taiyang Zhang, Lujun Zhu, Zhihao Yan +1
The light metal Al was predicted to have strong orbital Hall and Rashba effects from its bulk and interface, respectively. In this letter, we report experimental evidence that neit…
Absence of orbital current torque in a magnetic metal/Pt/CuOx trilayer
Zhihao Yan, Lujun Zhu, Xiangrui Qin +2
Naturally oxidized copper (CuOx) was cited as an exceptionally strong orbital-current source despite the keen debate over the concept of orbital current. Here, we report unambiguou…
Dominant spin Hall torque and negligible orbital Hall torque in α-W/ferromagnet heterostructures with artifacts-free angular momentum detectors
Taiyang Zhang, Lujun Zhu, Qianbiao Liu +1
α-phased W was theoretically predicted to have a negative spin Hall conductivity and a positive orbital Hall conductivity at the same time, leaving the physical origin of the curre…
Evidence for strong localization of orbital polarization
Taiyang Zhang, Lujun Zhu, Zhihao Yan +1
Whether orbital polarization propagates has become the most essential question of the blooming orbitronics that aims to generate non-local orbital torque and orbital pumping. Recen…
Linear Enhancement of Spin-Orbit Torques and Absence of Bulk Rashba-Type Spin Splitting in Perpendicularly Magnetized [Pt/Co/W]n Superlattices
Zhihao Yan, Zhengxiao Li, Lujun Zhu +2
The development of magnetic heterostructures with strong spin-orbit torques (SOTs), low impedance, strong perpendicular magnetic anisotropy (PMA), and good integration compatibilit…
Orbital torque switching in perpendicularly magnetized materials
Yuhe Yang, Ping Wang, Jiali Chen +13
The orbital Hall effect in light materials has attracted considerable attention for developing novel orbitronic devices. Here we investigate the orbital torque efficiency and demon…
Giant coercivity, resistivity upturn, and anomalous Hall effect in ferrimagnetic FeTb
Lijun Zhu, Lujun Zhu, Qianbiao Liu +1
Despite the blooming interest, the transition-metal rare-earth ferrimagnets have not been comprehensively understood in terms of their coercivity and transport properties. Here, we…
Strong Spin-Orbit Torque Induced by the Intrinsic Spin Hall Effect in Cr1-xPtx
Qianbiao Liu, Jingwei Li, Lujun Zhu +3
We report on a spin-orbit torque study of the spin current generation in Cr1-xPtx alloy, using the light 3d ferromagnetic Co as the spin current detector. We find that the dampingl…
Boosting spin-orbit torque efficiency in spin-current generator/magnet/oxide superlattices
Lijun Zhu, Jingwei Li, Lujun Zhu +1
Efficient manipulation of magnetic materials is essential for spintronics. In spin-current generator/magnet bilayers, the efficiency of spin-orbit torques per magnetic layer thickn…
Interfacial Dzyaloshinskii-Moriya interaction and spin-orbit torque in Au1-xPtx/Co bilayers with varying interfacial spin-orbit coupling
Lijun Zhu, Lujun Zhu, Xin Ma +2
The quantitative roles of the interfacial spin-orbit coupling (SOC) in Dzyaloshinskii-Moriya interaction (DMI) and dampinglike spin-orbit torque (τDL) have remained unsettled after…
Intrinsic nature of the giant spin Hall conductivity of Pt
Lijun Zhu, Lujun Zhu, Manling Sui +2
More than a decade after the first theoretical and experimental studies of the spin Hall conductivity (SHC) of Pt, both its dominant origin and amplitude remain in dispute. Resolvi…
