Manipulating 1-dimensinal skyrmion motion by external magnetic field gradient
Jaehun Cho, Eiiti Tamura, Chaozhe Liu +7
We have investigated an analytic formula of the 1-dimensional magnetic skyrmion dynamics under external magnetic field gradient. We find excellent agreement between the analytical…
Skyrmion Brownian circuit implemented in a continuous ferromagnetic thin film
Yuma Jibiki, Minori Goto, Eiiti Tamura +9
The fabrication of a skyrmion circuit which stabilizes skyrmions is important to realize micro- to nano-sized skyrmion devices. One example of promising skyrmion-based device is Br…
Quantitative agreement of Dzyaloshinskii-Moriya interactions for domain-wall motion and spin-wave propagation
Dae-Yun Kim, Nam-Hui Kim, Yong-Keun Park +10
The magnetic exchange interaction is the one of the key factors governing the basic characteristics of magnetic systems. Unlike the symmetric nature of the Heisenberg exchange inte…
Asymmetric hysteresis for probing Dzyaloshinskii-Moriya interaction
Dong-Soo Han, Nam-Hui Kim, June-Seo Kim +8
The interfacial Dzyaloshinskii-Moriya interaction (DMI) is intimately related to the prospect of superior domain-wall dynamics and the formation of magnetic skyrmions. Although som…
Interfacial Dzyaloshinskii-Moriya interaction, surface anisotropy energy,and spin pumping at spin orbit coupled Ir/Co interface
Nam-Hui Kim, Jinyong Jung, Jaehun Cho +5
The interfacial Dzyaloshinskii-Moriya interaction (iDMI), surface anisotropy energy, and spin pumping at the Ir/Co interface are experimentally investigated by performing Brillouin…
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…
Thickness dependence of the interfacial Dzyaloshinskii-Moriya interaction in inversion symmetry broken systems
Jaehun Cho, Nam-Hui Kim, Sukmock Lee +9
In magnetic multilayer systems, a large spin-orbit coupling at the interface between heavy metals and ferromagnets can lead to intriguing phenomena such as the perpendicular magnet…
Effect of annealing temperature on exchange stiffness of CoFeB thin films
Jaehun Cho, Jinyong Jung, Shin-Yong Cho +1
We investigate the exchange stiffness constants of 28-nm-thick CoFeB film using Brillouin light scattering. Series of CoFeB films are prepared on the MgO(001) substrate with or wit…
