Anomalous spin-orbit torque switching due to field-like torque-assisted domain wall reflection
Jungbum Yoon, Seo-Won Lee, Jae Hyun Kwon +5
Spin-orbit torques (SOT) allow the electrical control of magnetic states. Current-induced SOT switching of the perpendicular magnetization is of particular technological importance…
Giant nonreciprocal emission of spin waves in Ta/Py bilayers
Jae Hyun Kwon, Jungbum Yoon, Praveen Deorani +5
Spin waves are propagating disturbances in the magnetization of magnetic materials. One of their interesting properties is the nonreciprocity, exhibiting that their amplitude depen…
Spin orbit torques and Dzyaloshinskii-Moriya interaction in dual-interfaced Co-Ni multilayers
Jiawei Yu, Xuepeng Qiu, Yang Wu +5
We study the spin orbit torque (SOT) and Dzyaloshinskii-Moriya interaction (DMI) in the dual-interfaced Co-Ni perpendicular multilayers. Through the combination of top and bottom l…
Spin wave non-reciprocity and beating in permalloy by time-resolved magneto-optical Kerr effect
Siddharth Rao, Jungbum Yoon, Jan Rhensius +2
We have studied the propagation characteristics of spin wave modes in a permalloy stripe by time-resolved magneto-optical Kerr effect techniques. We observe a beating interference…
Direct observation of the Dzyaloshinskii-Moriya interaction in a Pt/Co/Ni film
Kai Di, Vanessa Li Zhang, Hock Siah Lim +6
The interfacial Dzyaloshinskii-Moriya interaction (DMI) in an in-plane anisotropic Pt(4nm)/Co(1.6nm)/Ni(1.6nm) film has been directly observed by Brillouin spectroscopy. It is mani…
Effect of spin transfer torque on the magnetic domain wall ferromagnetic resonance frequency in the nanowires
Jungbum Yoon, Chun-Yeol You, Younghun Jo +2
We investigate the influence of the domain wall ferromagnetic resonance frequency on the spin transfer torque in a ferromagnetic nanowire. By employing micromagnetic simulations wi…
