Strain-Mediated Lattice Reconstruction Enhances Ferromagnetism in Cr2Ge2Te6/WTe2 van der Waals Heterobilayers
Franz Herling, Mireia Torres-Sala, Dorye L. Esteras +17
Van der Waals (vdW) heterostructures enable tailored electronic and magnetic phases by stacking atomically thin layers with pristine interfaces. Here, we investigate fully 2D Cr2Ge…
Field-free superconducting diode effect in layered superconductor FeSe
Utane Nagata, Motomi Aoki, Akito Daido +7
The superconducting diode effect (SDE), where zero-resistance states appear nonreciprocally during current injection, is receiving tremendous interest in both fundamental and appli…
Gigantic Anisotropy of Self-Induced Spin-Orbit Torque in Weyl Ferromagnet Co2MnGa
Motomi Aoki, Yuefeng Yin, Simon Granville +6
Spin-orbit torque (SOT) is receiving tremendous attention from both fundamental and application-oriented aspects. Co2MnGa, a Weyl ferromagnet that is in a class of topological quan…
Anomalous sign inversion of spin-orbit torque in ferromagnetic/nonmagnetic bilayer systems due to self-induced spin-orbit torque
Motomi Aoki, Ei Shigematsu, Ryo Ohshima +3
Self-induced spin-orbit torques (SI-SOTs) in ferromagnetic (FM) layers have been overlooked when estimating the spin Hall angle (SHA) of adjacent nonmagnetic (NM) layers. In this w…
All-electric spin device operation using the Weyl semimetal, WTe, at room temperature
Kosuke Ohnishi, Motomi Aoki, Ryo Ohshima +4
Topological quantum materials (TQMs) possess abundant and attractive spin physics, and a Weyl semimetal is the representative material because of the generation of spin polarizatio…
Observation of gigantic spin conversion anisotropy in bismuth
Naoki Fukumoto, Ryo Ohshima, Motomi Aoki +9
Whilst the g-factor can be anisotropic due to the spin-orbit interaction (SOI), its existence in solids cannot be simply asserted from a band structure, which hinders progress on s…
Inplane spin orbit torque magnetization switching and its detection using the spin rectification effect at sub-GHz frequencies
Motomi Aoki, Ei Shigematsu, Ryo Ohshima +4
Inplane magnetization reversal of a permalloy/platinum bilayer was detected using the spin rectification effect. Using a sub GHz microwave frequency to excite spin torque ferromagn…
