Oscillatory spin-orbit torque switching induced by field-like torques
Jong Min Lee, Jae Hyun Kwon, Rajagopalan Ramaswamy +7
Deterministic magnetization switching using spin-orbit torque (SOT) has recently emerged as an efficient means to electrically control the magnetic state of ultrathin magnets. The…
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…
Study of spin dynamics and damping on the magnetic nanowire arrays with various nanowire widths
Jaehun Cho, Yuya Fujii, Katsunori Konioshi +7
We investigate the spin dynamics including Gilbert damping in the ferromagnetic nanowire arrays. We have measured the ferromagnetic resonance of ferromagnetic nanowire arrays using…
In-plane angular dependence of the spin-wave nonreciprocity of an ultrathin film with Dzyaloshinskii-Moriya interaction
Vanessa Li Zhang, Kai Di, Hock Siah Lim +6
The nonreciprocal propagation of spin waves in an ultrathin Pt/Co/Ni film has been measured by Brillouin light scattering. The frequency nonreciprocity, due to the interfacial Dzya…
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…
Micromagnetic analysis of magnetic noise in ferromagnetic nanowires
Jungbum Yoon, Chun-Yeol You, Younghun Jo +2
We investigate the magnetic thermal noise in magnetic nanowires with and without a domain wall by employing micromagnetic simulations. The magnetic thermal noise due to random ther…
