Dynamics of a nanoscale ferromagnetic vortex
Jun Seok Seo, Se Kwon Kim
We propose a ferromagnetic vortex stabilized by the interfacial Dzyaloshinskii--Moriya interaction (iDMI) and investigate its properties through theoretical analysis and micromagne…
Superconducting diode effect in magnetic superconductors realized by nonreciprocal domain-wall dynamics
Dong Hui Han, Suk Bum Chung, Se Kwon Kim
A superconducting diode effect is shown to arise in ferromagnetic superconductors through the nonreciprocal dynamics of magnetic domain walls. Specifically, we show that current-dr…
Helicity-Selective Phonon Absorption and Phonon-Induced Spin Torque from Interfacial Spin-Lattice Coupling
Gyungchoon Go, Se Kwon Kim
In magnetic heterostructures with broken inversion symmetry, the Rashba effect gives rise to a gradient-free interaction between magnons and phonons, which we term interfacial spin…
Optimized control protocols for stable skyrmion creation using deep reinforcement learning
Ji Seok Song, Se Kwon Kim, Kyoung-Min Kim
Generating stable magnetic skyrmions is essential for the practical application of skyrmion-based spintronic devices in thermally agitating environments. Here, we present a deep re…
Two-Dimensional Twisted Ferromagnetic Domain Wall as a Spin-Wave Diffraction Grating
Ehsan Faridi, Se Kwon Kim, Giovanni Vignale
We present a theoretical study of spin-wave scattering by a twisted domain wall (DW) in a two-dimensional ferromagnet with easy-axis anisotropy. While the twisted DW generates an e…
