Non-Hermitian control of helicity-selective antiferromagnetic resonance
Masato Todani, Satoshi Iihama, Yuto Moritake +1
We study non-Hermitian antiferromagnetic resonance in an antiferromagnetic insulator/nonmagnetic metal junction with sublattice-dependent damping and spin-orbit torque. By formulat…
Distinct memory properties in spin-wave reservoir computing based on synthetic antiferromagnet
Takumu Shinkai, Satoshi Iihama, Kensuke Hayashi +3
Spin-wave-based physical reservoir computing (RC) is a promising candidate for energy-efficient physical implementations of artificial intelligence because of its potential for nan…
Single-Shot Magnetization Reversal in Ferromagnetic Spin Valves Enabled via Heat Control
Kazuaki Ishibashi, Junta Igarashi, Alberto Anadón +7
We study laser induced ultrafast magnetization reversal in a ferromagnetic spin valve by comparing the effects of direct laser excitation and ultrashort hot electron pulses. A wedg…
Light-induced torque in ferromagnetic metals via orbital angular momentum generated by photon-helicity
Koki Nukui, Satoshi Iihama, Kazuaki Ishibashi +7
We investigated photon-helicity-induced magnetization precession in CoPt alloy thin films. In addition to field-like torque, attributable to magnetic field generation…
