Microwave Kerr/Faraday Resonance in Two-dimensional Chiral Superconductors
Taiki Matsushita, Jun'ichi Ieda, Yasufumi Araki +3
We investigate the polar Kerr and Faraday effects in two-dimensional multiband chiral superconductors. We show that the clapping modes--the relative phase and amplitude oscillation…

Theory of electric reactance emerging from spin Hall effect
Yasufumi Araki, Jun'ichi Ieda
The spin Hall effect in a heavy metal intercorrelates an AC electric current to the magnetization dynamics in an adjacent ferromagnet, which manifests as an electric reactance in t…

Single-layer spin-orbit-torque magnetization switching due to spin Berry curvature generated by minute spontaneous atomic displacement in a Weyl oxide
Hiroto Horiuchi, Yasufumi Araki, Yuki K. Wakabayashi +8
Spin Berry curvature characterizes the band topology as the spin counterpart of Berry curvature and is crucial in generating novel spintronics functionalities. By breaking the crys…
