Magnetic Transition in Monolayer VSe2 via Interface Hybridization
Wen Zhang, Lei Zhang, Ping Kwan Johnny Wong +6
Magnetism in monolayer (ML) VSe2 has attracted broad interest in spintronics while existing reports have not reached consensus. Using element-specific X-ray magnetic circular dichr…
Squeezed metallic droplet with tunable Kubo gap and charge injection in transition metal dichalcogenides
Jiaren Yuan, Yuanping Chen, Yuee Xie +6
Shrinking the size of a bulk metal into nanoscale leads to the discreteness of electronic energy levels, the so-called Kubo gap. Renormalization of the electronic properties with a…
Protected valley states and generation of valley- and spin-polarized current in monolayer MA2Z4
Jiaren Yuan, Qingyuan Wei, Minglei Sun +4
The optical selection rules obeyed by two-dimensional materials with spin-valley coupling enable the selective excitation of carriers. We show that six members of the monolayer MA2…
Bilayer twisting as a mean to isolate connected flat bands in a Kagome lattice through Wigner crystallization
Jing Wu, Yuee Xie, Mingxing Chen +4
The physics of flat band is novel and rich but difficult to access. In this regard, recently twisting of bilayer van der Waals (vdW)-bounded two-dimensional (2D) materials has attr…
Origin and Large Enhancement of Large Spin Hall Angle in Weyl Semimetals LaAl (=Si, Ge)
Truman Ng, Yongzheng Luo, Jiaren Yuan +3
We study the origin of the strong spin Hall effect (SHE) in a recently discovered family of Weyl semimetals, LaAl (=Si, Ge) via a first-principles approach with maximally loc…
In-situ study of oxygen exposure effect on spin-orbit torque in Pt/Co bilayers in ultrahigh vacuum
Hang Xie, Jiaren Yuan, Ziyan Luo +2
Oxygen incorporation has been reported to increase the current-induced spin-orbit torque in ferromagnetic heterostructures, but the underlying mechanism is still under active debat…
Intrinsic skyrmions in monolayer Janus magnets
Jiaren Yuan, Yumeng Yang, yongqing Cai +5
Skyrmions are localized solitonic spin textures with protected topology, which are promising as information carriers in ultra-dense and energy-efficient logic and memory devices. R…
Unveiling the role of Co-O-Mg bond in magnetic anisotropy of Pt/Co/MgO using atomically controlled deposition and in-situ electrical measurement
Yumeng Yang, Jiaren Yuan, Long Qi +7
Despite the crucial role of interfacial perpendicular magnetic anisotropy in Co(Fe)/MgO based magnetic tunnel junction, the underlying mechanism is still being debated. Here, we re…
