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…
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…
Magnetoelastic Coupling-Driven Chiral Spin Textures: A Skyrmion-Antiskyrmion-Like Array
Gyungchoon Go, Se Kwon Kim
We theoretically demonstrate that sufficiently strong magnetoelastic coupling can change the ground state of otherwise uniform spin systems to chiral spin configurations. More spec…
Thermal magnetoresistance from magnon scattering from a domain wall in an antiferromagnetic insulator
Ehsan Faridi, Se Kwon Kim, Giovanni Vignale
We theoretically investigate magnon heat transport in an antiferromagnetic (AFM) insulator containing a domain wall (DW) in the presence of a magnetic field applied along the easy…
Control of spin-wave polarity and velocity using a ferrimagnetic domain wall
Ehsan Faridi, Giovanni Vignale, Se Kwon Kim
We present a theoretical study of the scattering of spin waves by a domain wall (DW) in a ferrimagnetic (FiM) spin chain in which two sublattices carry spins of unequal magnitudes.…
Tunable Ultrafast Dynamics of Antiferromagnetic Vortices in Nanoscale Dots
Ji Zou, Even Thingstad, Se Kwon Kim +2
Topological vortex textures in magnetic disks have garnered great attention due to their interesting physics and diverse applications. However, up to now, the vortex state has main…
