Temperature dependence of charge-to-spin conversion in rhombohedral (110) bismuth thin film
K. Tatsuoka, N. Fukumoto, S. Sakamoto +7
The amplitude of charge-to-spin conversion, namely the spin Hall effect (SHE), in bismuth (Bi) strongly depends on its crystal orientation. The conversion efficiency at room temper…
Potentiometric detection of spin polarization expected at the surface of FeTe0.6Se0.4 in the effective p-wave superconducting state
K. Ohnishi, R. Ohshima, T. Nishijima +7
Nowadays, the quest for non-Abelian anyons is attracting tremendous attention. In particular, a Majorana quasiparticle has attracted great interest since the non-Abelian anyon is a…
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…
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…
