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…
Perpendicular magnetic anisotropy tuning of macrospin-to-vortex transitions in Co-based artificial spin-vortex ice
Yu Maruyama, Amrit Kumar Mondal, Bijaya Kharel +4
We investigate the macrospin-to-vortex (MS-to-V) transition in Co-based artificial spin-vortex ice (ASVI) in the presence of perpendicular magnetic anisotropy (PMA) by spin-wave sp…
Enhancement of spin-wave nonreciprocity and group velocity in a low-wavenumber regime
Shion Yoshimura, Shugo Yoshii, Ryo Ohshima +1
Nonreciprocity of spin waves is essential for components such as magnetic isolators and circulators used in spin-wave-based computing. A ferromagnetic (FM) bilayer exhibits signifi…
Circular photogalvanic effect in an inversion-symmetry-broken bilayer germanium nanosheet
Taiki Nishijima, Ei Shigematsu, Ryo Ohshima +7
Spin-to-charge conversion in monolayer and bilayer germanium(Ge) nanosheets was demonstrated via the circular photogalvanic effect (CPGE). The CPGE current generated in a spin-spli…
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…
Electrical transport properties of atomically thin WSe2 using perpendicular magnetic anisotropy metal contacts
S. Gupta, R. Ohshima, Y. Ando +3
Tungsten diselenide, WSe2 shows excellent properties and become very promising material among two dimensional semiconductors. Wide band gap and large spin-orbit coupling along with…
