Tunable Magnon Polaritons via Eddy-Current-Induced Dissipation in Metallic-Banded YIG Spheres
Tatsushi Uno, Shugo Yoshii, Sotaro Mae +4
We demonstrate a robust method to dynamically tune magnon dissipation in yttrium iron garnet spheres by equipping a metallic band around the sphere's equator, enabling precise cont…

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…
